h(x) is the image after f(x) is horizontally stretched by a scale factor of 4

Step-by-step explanation:

Given

$h(x) = \frac{1}{4}x^2$

f(x) = x^2

Required

Compare h(x) to f(x)

We have:

$h(x) = \frac{1}{4}x^2$

Substitute f(x) = x^2

$h(x) = \frac{1}{4}f(x)$

This means that f(x) is stretched horizontally by a scale factor of 4 to get h(x)
