Finding a Vertical Compression of a Tabular Function

A function $f$ is given as the table. Create a table for the function $g\left(x\right)=\frac{1}{2}f\left(x\right).$

$$\begin{array}{ccccc}x& \text{2}& \text{4}& \text{6}& \text{8}\\ f\left(x\right)& \text{1}& \text{3}& \text{7}& \text{11}\end{array}$$
