Find X When F(x) Equals -3 A Table Function Problem

The provided table offers a concise snapshot of a function, denoted as f(x). This function establishes a clear relationship between input values (represented by x) and their corresponding output values (represented by f(x)). In essence, for each x value, the function f dictates a specific output. Examining the table allows us to discern this relationship and extract crucial information about the function's behavior. Delving into the table, we find a set of ordered pairs that vividly depict how the function transforms various inputs. For instance, when x is -4, the function f maps it to -66. Similarly, when x is 0, the output f(x) is -2. This pattern continues across the table, revealing the function's response to a spectrum of input values. Analyzing this data is akin to unraveling the function's inner workings, allowing us to predict its behavior and answer specific questions about its properties. By carefully scrutinizing the table, we can gain insights into the function's trend, identify potential patterns, and ultimately understand its mathematical nature. The table serves as a powerful tool for visualizing and interpreting the function's behavior, making it easier to analyze and draw meaningful conclusions. For instance, we might be interested in finding the input value that results in a specific output, or we might want to understand how the output changes as the input increases or decreases. The table provides the necessary data to address these questions and gain a comprehensive understanding of the function. In this particular case, we are presented with a specific question: "When f(x) = -3, what is x?" To answer this, we need to carefully examine the table and identify the row where the f(x) value matches -3. Once we locate that row, we can simply read off the corresponding x value, which will be our answer. This process highlights the direct and practical way in which the table can be used to solve problems related to the function f(x). The clarity and organization of the table make it an efficient tool for analyzing the function and extracting the desired information.

Decoding the Function's Behavior

To fully grasp the essence of the function f(x) as it is presented in the table, it's crucial to recognize the fundamental concept of a function itself. At its core, a function is a mathematical entity that establishes a unique correspondence between elements of two sets: the input set (domain) and the output set (range). In simpler terms, it's like a machine that takes an input, processes it according to a specific rule, and produces a unique output. The table we are examining provides a set of these input-output pairs, effectively giving us a glimpse into the workings of this function. Each row in the table represents a specific instance of this input-output relationship. The left column lists the input values (x), while the right column displays the corresponding output values (f(x)). This pairing is crucial because it allows us to directly observe how the function transforms different inputs. For example, the row where x = -4 and f(x) = -66 tells us that when the function receives -4 as input, it produces -66 as output. Similarly, the row where x = 0 and f(x) = -2 indicates that the function maps 0 to -2. By systematically analyzing each row in the table, we can start to build a comprehensive picture of the function's behavior. We can observe trends, identify patterns, and even make educated guesses about the underlying rule that governs the function's transformation of inputs into outputs. This understanding is essential for answering questions about the function, such as the one posed in this problem: "When f(x) = -3, what is x?" To answer this, we need to search the table for the row where the f(x) value is -3 and then identify the corresponding x value. This simple task highlights the power of the table as a tool for understanding and working with functions. It provides a clear and concise representation of the function's behavior, allowing us to quickly access the information we need. Furthermore, the table allows us to easily visualize the function's behavior, making it easier to identify trends and patterns. This can be particularly useful when dealing with functions that are complex or difficult to express algebraically.

Solving for x when f(x) = -3

The key to answering the question lies in carefully examining the table provided. The question, "When f(x) = -3, what is x?" requires us to find the input value (x) that corresponds to a specific output value (f(x) = -3). This is a common type of problem when working with functions, and the table provides a direct way to find the solution. We simply need to scan the column representing f(x) and locate the row where the value is -3. Once we've found that row, we can then look at the corresponding value in the x column to determine the input that produces the output of -3. This process is straightforward and highlights the utility of the table as a tool for analyzing functions. Instead of having to work with an algebraic equation or a complex formula, we can simply look up the answer directly in the table. This is particularly helpful when dealing with functions that are defined empirically, meaning that their values are determined through observation or experimentation rather than through a mathematical formula. In such cases, a table of values might be the most convenient or even the only way to represent the function. In the given table, as we scan the f(x) column, we come across the value -3 in the row where x is -1. This immediately tells us that when x = -1, f(x) is indeed -3. Therefore, the answer to the question is x = -1. This simple example demonstrates the power of using a table to understand and work with functions. It provides a visual representation of the function's behavior, making it easy to find specific values and answer related questions. The table acts as a readily accessible database of input-output pairs, allowing us to quickly determine the function's response to different inputs. This method is particularly useful when dealing with discrete functions, where the input values are distinct and separate, as opposed to continuous functions, where the input values can take on any value within a range.

Identifying the Correct Answer

After carefully examining the table and locating the row where f(x) equals -3, we can definitively identify the corresponding x value. As we've established, this process involves a simple lookup within the table, a direct way to find the solution without the need for complex calculations or algebraic manipulations. This highlights the advantage of using tables to represent functions, especially when dealing with specific input-output relationships. In our case, the table clearly shows that when f(x) is -3, the value of x is -1. Therefore, we can confidently conclude that the correct answer is D. -1. The other options presented (A. -29, B. -10, and C. -3) are incorrect because they do not match the relationship defined in the table. Option A, -29, is the output f(x) when x is -3, not the input when f(x) is -3. Option B, -10, is the output f(x) when x is -2. Option C, -3, is an output value, but it corresponds to an input value of -1, which is the correct answer, but it misinterprets the question by providing the f(x) value instead of the x value. This careful elimination of incorrect options further reinforces the accuracy of our chosen answer, D. -1. The ability to quickly and accurately identify the correct answer based on the table demonstrates the practical utility of this representation of a function. It allows us to solve problems directly, without relying on potentially cumbersome algebraic methods. Furthermore, the table provides a clear and visual representation of the function's behavior, making it easier to understand the relationship between inputs and outputs. This understanding is crucial for solving problems and making predictions about the function's behavior in different contexts. The table serves as a valuable tool for analyzing and interpreting functions, particularly in situations where we are interested in specific input-output pairs.

Therefore, the answer is D. -1
