Question

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

A. The graph of g(x) is shifted 3 units to the right.
B. The graph of g(x) is horizontally stretched by a factor of 3.
C. The graph of g(x) is horizontally compressed by a factor of 3.
D. The graph of g(x) is vertically compressed by a factor of 3.

Answer 1

since it would be (1/3) squared, it would be a vertical compression of 9. since the x is not the output, it would make a horizontal stretch factor of 3.
