See the entire solution process below:

#### Explanation:

Substitute $\textcolor{red}{- 6}$ for each occurrence of $\textcolor{red}{x}$ and then calculate.

$p \left(\textcolor{red}{x}\right) = 3 \textcolor{red}{x}$

Becomes:

$p \left(\textcolor{red}{- 6}\right) = 3 \times \textcolor{red}{- 6}$

$p \left(\textcolor{red}{- 6}\right) = - 18$
