Answer:

g(x) is horizontally stretched by a factor of 1/5

Step-by-step explanation:

Given

$f(x) = x^2$

$g(x) = (\frac{x}{5})^2$

Require

Determine the relationship between f(x) and g(x)

$f(x) = x^2$

$g(x) = (\frac{x}{5})^2$

Express g(x) in terms of f(x)

$g(x)=f(\frac{x}{5})$

This can further be simplified as:

$g(x)=f(\frac{1}{5}x)$

When a function is represented as:

$g(x) = f(cx)$

Where c < 1,

Then the type of translation is a horizontal stretch (stretch in the x direction)

By comparison: $g(x) = f(cx)$ and $g(x)=f(\frac{1}{5}x)$

$c = \frac{1}{5}$

This means that: g(x) is horizontally stretched by a factor of 1/5
