Question

use the following function - rule to find f(-17).
f(x)=-4 - \frac{x}{17}
f(-17)= square

Explanation:

Step1: Substitute x = - 17

Substitute $x=-17$ into $f(x)=-4-\frac{x}{17}$.
$f(-17)=-4-\frac{-17}{17}$

Step2: Simplify the fraction

Simplify $\frac{-17}{17}=-1$.
$f(-17)=-4 - (-1)$

Step3: Simplify the subtraction

$-4-(-1)=-4 + 1$.
$f(-17)=-3$

Answer:

$-3$
