Key Concepts

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.
