Question

evaluate the function. put your answer in function notation.
find $f(8)$ if
$f(x) = -4x^2 - 3x - 6$

Explanation:

Step1: Substitute $x=8$ into $f(x)$

$f(8) = -4(8)^2 - 3(8) - 6$

Step2: Calculate the squared term

$8^2 = 64$, so $-4(64) = -256$

Step3: Calculate the linear term

$3(8) = 24$, so $-3(8) = -24$

Step4: Sum all terms

$f(8) = -256 - 24 - 6$

Answer:

$f(8) = -286$
