Question

Help with this math please

Answer 1

The answer is -20 .

Explanation:

You have to substitute x = -4 into the function :

`f(x) = 3x - 8`

`f( - 4) = 3( - 4) - 8`

`f( - 4) = - 20`

Answer 2

Explanation:

f(x) = 3x - 8

f(-4) = 3*(-4) - 8

f(-4) = -12 - 8

f(-4) = - 20

-20 is what goes in the box.
