Using a Table to Evaluate a Composite Function

Using the table, evaluate $f\left(g\left(3\right)\right)$ and $g\left(f\left(3\right)\right).$

$$\begin{array}{ccc}x& f\left(x\right)& g\left(x\right)\\ \text{1}& \text{6}& \text{3}\\ \text{2}& \text{8}& \text{5}\\ \text{3}& \text{3}& \text{2}\\ \text{4}& \text{1}& \text{7}\end{array}$$
