6-46.

Two function machines, $f\left(x\right) = 5x − 3$ and $g\left(x\right) = \left(x − 1\right)^{2}$, are shown below. Suppose $f\left(3\right)$, (not $x = 3$), is dropped into the $g\left(x\right)$ machine. This is written as $g\left(f\left(3\right)\right)$. What is this output?

$f\left(3\right) = 12$ so $g\left(f\left(3\right)\right) = g\left(12\right) = 121$
