To find the value of $(h \circ f)(4)$, you first need to understand that $(h \circ f)(4)$ means applying the function $f$ to $4$, and then applying the function $h$ to the result of $f(4)$.

This process can be broken down into two steps:

1. Compute $f(4)$: Find the value of the function $f$ at $x = 4$.
2. Compute $h(f(4))$: Take the result from step 1 and use it as the input for the function $h$.

To solve the problem, I'll need the explicit forms of the functions $f(x)$ and $h(x)$. Could you please provide them?
