the graph of function  g  is a vertical stretch of the graph of function  f  by a factor of 5.which equation describes function  g? a) g(x)=5f(x)b)  g(x)=f(5x)c)  g(x)=1/5f(x)d)  g(x)=f(x/5)

We are given a function f(x).

And function g(x) is the function get after transformation of f(x) a vertical stretch of the graph of function f by a factor of 5.

We know transformation rule when it's a vertical stretch by a given scale factor.

y= k f(x) : f(x) is stretch by a scale factor of k. Where |k| > 0.

So, we need to multiply given function f(x) by given scale factor 5.

So,  g(x) = 5 f(x).

the answer is 11.2 (i know i’m late)
