WebJan 16, 2024 · Using the functions provided, find f(g(x)) and g(f(x)). Determine whether the composition of the functions is commutative. f(x) = 2x + 1 g(x) = 3 − x Solution Let’s begin by substituting g(x) into f(x). f(g(x)) = 2(3 − x) + 1 = 6 − 2x + 1 = 7 − 2x Now we can substitute f(x) into g(x). g(f(x)) = 3 − (2x + 1) = 3 − 2x − 1 = 2 − 2x WebGiven two functions f ( x) and g ( x), test whether the functions are inverses of each other. Determine whether f ( g ( x)) = x or g ( f ( x)) = x. If either statement is true, then both are true, and g = f − 1 and f = g − 1. If either statement is false, then both are false, and g ≠ f − 1 and f ≠ g − 1. Example 2
