# How do you calculate f(x) for the given domain values f(x) = -2x -14; x = -1, -5, -10, -15, 12?

$- 12 , - 4 , 6 , 16 , - 38$

#### Explanation:

$\text{substitute the given values for x in the domain into f(x)}$

$f \left(\textcolor{red}{- 1}\right) = - 2 \left(\textcolor{red}{- 1}\right) - 14 = 2 - 14 = - 12$

$f \left(\textcolor{red}{- 5}\right) = - 2 \left(\textcolor{red}{- 5}\right) - 14 = 10 - 14 = - 4$

$\text{ I'll leave the others for you to do}$
