Given: A graph of the function

Required: To describe the graph of the function

[tex]g(x)=4ln(x)[/tex]

Explanation: Let c be a given non-zero real number. Then for a known function

[tex]y=f(x)[/tex]

we have for a function

[tex]g(x)=cf(x)[/tex]

Then, if c>1 the graph g(x) stretches vertically and if 0The given function g(x) can be written as

[tex]\begin{gathered} g(x)=4ln(x) \\ =2\cdot2ln(x) \\ =2f(x) \end{gathered}[/tex]

Hence, the given graph will vertically stretch by 2 units.

Final Answer: Option A is correct.
