Composition of Functions · Exercise 58

Use the function values for $f\text{and}g$ shown in the table to evaluate each expression.
$$\begin{array}{ccc}x& f\left(x\right)& g\left(x\right)\\ \text{0}& \text{7}& \text{9}\\ \text{1}& \text{6}& \text{5}\\ \text{2}& \text{5}& \text{6}\\ \text{3}& \text{8}& \text{2}\\ \text{4}& \text{4}& \text{1}\\ \text{5}& \text{0}& \text{8}\\ \text{6}& \text{2}& \text{7}\\ \text{7}& \text{1}& \text{3}\\ \text{8}& \text{9}& \text{4}\\ \text{9}& \text{3}& \text{0}\end{array}$$

$f\left(g\left(8\right)\right)$

Its source prints no answer for this problem, so there's nothing to check against.
