Question

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

Answer 1

We conclude that:

• 
  `f\left(-3\right)=77`

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`
