We conclude that:

$f\left(-3\right)=77$

Step-by-step explanation:

Given the function

f(x) = 11 - 6(x - 8)

Important Tip:

In order to determine f(-3), all we need is to substitute x = -3 in the function equation

substitute x = -3 in the equation

f(x) = 11 - 6(x - 8)

f(-3) = 11 - 6(-3 - 8)

$f\left(-3\right)\:=\:11-\left(-66\right)$

$f\left(-3\right)\:=\:11+66$ ∵ Apply rule -(-a) = a

$f\left(-3\right)=77$

Therefore, we conclude that:

$f\left(-3\right)=77$
