See the solution process below:

#### Explanation:

To solve this problem substitute $\textcolor{red}{a + 4}$ for each occurrence of $\textcolor{red}{a}$ in the function $w \left(a\right)$

$w \left(\textcolor{red}{a}\right) = \textcolor{red}{a} + 3$ becomes:

$w \left(\textcolor{red}{a + 4}\right) = \textcolor{red}{a + 4} + 3$

$w \left(\textcolor{red}{a + 4}\right) = a + 7$
