If you horizontally stretch the linear parent function f(x) = x by a factor of 2, what is the equation of the new function?

a. g(x) = 1/2x
b. g(x) = x-2
c. g(x) = 2x
d. g(x) = 2-x

ANSWER

C.

EXPLANATION

The linear parent function is

When this linear function is horizontally stretched by a factor of 'a', then the equation becomes

In this case,

This implies that,
