I need to know the answer to this like asap

Answer 1

Explanation

In general, a vertically compression of a function f(x) is obtained by the transformation:

$f(x)\rightarrow g(x)=\frac{1}{k}\cdot f(x).$

Where k > 1 is the factor of compression.

In this case we have f(x) = |x| and k = 4. Applying the transformation above, we get:

$g(x)=\frac{1}{4}\cdot|x|.$Answer

C.

$g(x)=\frac{1}{4}|x|$
