If you horizontally stretch the linear parent function, f(x) = x, by a factor of 3, what is the equation of the new function?
A. g(x) = x - 3
B. g(x) = 3x
O C. g(x) = 3 - x
D. g(x) = 3 *
SUBMIT

The equation of the new function is

Step-by-step explanation:

Horizontally stretching a function:

Horizontally stretching a function f(x), by a factor of a, means that:

In this question:

, horizontally stretched by a factor of 3, so , and:

The equation of the new function is

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
