Question

The function f(x)=log4x is dilated to become g(x)=f(13x). What is the effect on f(x)?

Answer 1

Answer:

f(x) is compressed horizontally

Step-by-step explanation:

Given

$f(x) = \log(4x)$

$g(x) = f(13x)$

Required

The effect on f(x)

$g(x) = f(13x)$ implies that f(x) is horizontally compressed by 13.

So, we have:

$f(13) = \log(4 * 13x)$

$f(13) = \log(52x)$

So:

$g(13) = \log(52x)$
