Let $f(x) = \frac{x}{x+4}$ and $g(x) = x^2\text{.}$

Write the formula for the composite function $g(f(x))\text{.}$
Start by substituting the formula for $f(x)$ into the function $g\text{:}$
$g(f(x)) = g\big($ $\big)$
Then simplify the expression you wrote above, by using the formula for $f(x)$ as the input in the formula for the function $g\text{.}$
$g(f(x)) =$
