Below is the graph of f(x)=2in(x). how would you describe the graph of g(x)=4in(x)?

The statement which best describes the graph of g(x) is:

                Option: A

    A.  g(x) stretches f(x) vertically by a factor of 2.

We are given a original function f(x) as:

and a transformed function g(x) as:

We know that any transformation of the type:

  f(x) to a f(x) is a vertical stretch by a factor of a if a>1

and a vertical compression if a<1

Here we have:

i.e. g(x) is a vertical stretch of f(x) by a factor of 2.

sorry i dont know my friend
