Question

What is the effect on the graph of the function f(x) = 2x when f(x) is replaced with f(2/3x)?


A) vertical stretching

B) vertical compression

C) horizontal compression

D) horizontal stretching

Answer 1

Answer:

This will be an effect of vertical compression.

Step-by-step explanation:

We have to determine the change on the graph of the function f(x) = 2x when f(x) is replaced with $f(\frac{2}{3}x )$.

Therefore, $f(\frac{2}{3} x) = 2(\frac{2}{3}x )= \frac{4}{3} x$

It is clear that for the same value of x the y-value decreased by the factor $\frac{2}{3}$.

Hence, this will be an effect of vertical compression. ( Answer )

Answer 2

Answer:it’s horizontal stretching

Step-by-step explanation:

if you’re in usa test prep, it is NOT vertical compression.
