Question

Suppose f(x)=2^x and g(x)=2^1/3^x. Which statement best compares the graph of g(x) with the graph of f(x)?

Answer 1

Explanation:

y = f(dx): compress the graph of y = f(x) horizontally by d

y = f(d/c): stretch the graph of y = f(x) horizontally by d

Here, we are given y = f(x/3), thus, this is horizontally stretching the graph by 3.

Correct option: C
