The graph of function g is a vertical stretch of the graph of function f by a factor of 3. which equation describes function g? a. g(x)=3f(x) b. g(x)=f(3x) c. g(x)=13f(x) d. g(x)=f(x3)

Vertical stretch of function:

Suppose, we are given to vertically stretch any function f by 'a' units

so, we multiply y-value by 'a'

assume

new function is g(x)

so, we get

now, we are given

The graph of function g is a vertical stretch of the graph of function f by a factor of 3

so, a=3

so, we get
