Question

question given $f(x) = -x^2 + x - 17$, find $f(-8)$

Explanation:

Step1: Substitute $x=-8$

$f(-8) = -(-8)^2 + (-8) - 17$

Step2: Calculate squared term

$(-8)^2 = 64$, so $-(-8)^2 = -64$

Step3: Compute linear terms

$-64 + (-8) - 17 = -64 -8 -17$

Step4: Sum the values

$-64 -8 -17 = -89$

Answer:

$-89$
