Textbook Question

Use the table to evaluate the given compositions. <IMAGE>

g(ƒ(4))

Verified step by step guidance

Identify the functions involved: \( g(x) \) and \( f(x) \).

Determine the value of \( f(4) \) using the table provided.

Substitute the value of \( f(4) \) into the function \( g(x) \) to find \( g(f(4)) \).

Use the table to find the value of \( g(f(4)) \) by locating the corresponding output for the input obtained in the previous step.

Verify the steps to ensure the correct values were used from the table.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Function Composition

Function composition involves combining two functions where the output of one function becomes the input of another. For example, if you have functions f(x) and g(x), the composition g(f(x)) means you first apply f to x, then apply g to the result. Understanding this concept is crucial for evaluating expressions like g(f(4)).

Evaluating Functions

Evaluating a function means substituting a specific value into the function to find the output. For instance, if f(x) = x + 2, then f(4) = 4 + 2 = 6. This step is essential in function composition, as you need to evaluate the inner function before applying the outer function.

Order of Operations

The order of operations is a set of rules that dictates the sequence in which mathematical operations should be performed. In function composition, you must first evaluate the inner function before the outer function. This principle ensures that calculations are performed correctly and consistently, especially in complex expressions.
