Answer:

C. vertical compression

Explanation:


\left\begin{array}{ccc}f(-2)=8\\g(-2)=4\end{array}\right\}\Rightarrow g(x)=(1)/(2)f(x)\\\\\left\begin{array}{ccc}f(-1)=6\\g(-1)=3\end{array}\right\}\Rightarrow g(x)=(1)/(2)f(x)\\\left\begin{array}{ccc}f(0)=8\\g(0)=4\end{array}\right\}\Rightarrow g(x)=(1)/(2)f(x)\\\left\begin{array}{ccc}f(1)=14\\g(1)=7\end{array}\right\}\Rightarrow g(x)=(1)/(2)f(x)


\large\boxed{g(x)=(1)/(2)f(x)}

f(x - b) - shifted b units to the right

f(x + b) - shifted b units to the left

f(x) + b - shifted b units up

f(x) - b - shifted b units down

f(-x) - reflected across the y -axis

-f(x) - reflected across the x -axis

f(nx) - a horizontal compression by a factor of n

f(x/n) -a horizontal stretch by a factor of n

nf(x) - a vertical stretch by a factor of n

f(x)/n - a vertical compression by a factor of n
