Answer:
The new function is [tex]g(x)=3x[/tex]
Step-by-step explanation:
We are given the function [tex]f(x)=x[/tex].
Now, the function f(x) is vertically stretched by a factor of 3.
We know that,
Vertical stretch changes the function f(x) by [tex]kf(x)[/tex], where k is any constant.
So, we get that,
The vertically stretched function is [tex]g(x)=3f(x)[/tex] i.e. [tex]g(x)=3x[/tex].
Hence, the equation of the new function is [tex]g(x)=3x[/tex].
