Question

If you vertically stretch the linear parent function, Fx) = x, by multiplying by 3,what is the equation of the new function?A. G(x) = 3xB. G(x) = x+3C. G(x) = x-3D. G(x) = -3x

Answer 1

Option A is correct.

g(x) = 3x

Step-by-step explanation

Vertically stretching or compressing a given function, f(x), by a factor, k, gives a function g(x) given as

g(x) = k [f(x)]

For this question,

k = 3

f(x) = x

g(x) = 3x

Hope this Helps!!!
