Question

for the function $f(x)= -5x+2$, $f(-4)=$_.
$f(-4)=\square$ (simplify your answer.)

Explanation:

Step1: Substitute $x=-4$ into $f(x)$

$f(-4) = -5(-4) + 2$

Step2: Calculate the multiplication

$-5(-4) = 20$, so $f(-4) = 20 + 2$

Step3: Calculate the final sum

$20 + 2 = 22$

Answer:

22
