Question

Consider the graph of function g. If f(x) = x², which equation represents function g?

A) g(x) = f(2x)
B) g(x) = f(4x)
C) g(x) = 2f(x)
D) g(x) = f(1/2 x)

Answer 1

The equation that represents function g when f(x) = x² is g(x) = f(2x).

Step-by-step explanation:

The equation that represents function g when f(x) = x² is g(x) = f(2x). This means that the input to function f is multiplied by 2 before being passed to f, which squares the result.
