Question

If f(x) = 11 - 6(x - 8), what is f(-3)?

Answer 1

Answer:

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:

• $f\left(-3\right)=77$
