# How do you evaluate the function when x = -3, 0, and 2 for p(x) = -7x - 5?

Jul 28, 2017

$16 , - 5 , - 19$

#### Explanation:

$\text{by substituting each of the values in turn into p(x)}$

$\Rightarrow p \left(\textcolor{red}{- 3}\right) = \left(- 7 \times \textcolor{red}{- 3}\right) - 5 = 21 - 5 = 16$

$\Rightarrow p \left(\textcolor{red}{0}\right) = \left(- 7 \times \textcolor{red}{0}\right) - 5 = 0 - 5 = - 5$

$\Rightarrow p \left(\textcolor{red}{2}\right) = \left(- 7 \times \textcolor{red}{2}\right) - 5 = - 14 - 5 = - 19$
