Question

HELP ASAP! I need the answer to all 3 of these questions.

If f(x)=3x+2, find f(8).

If f(x)=3x+2, find f(-2)

If f(x)=3x+2, find f(-2)

Answer 1

I think that number one is 26, two is -4, and three is -4

Explanation:

To solve for number one replace 8 with (x) so 3(8) + 2. 3 x 8 = 24 and 24+2 = 26

Numbers 2 and 3 appear to be the same problem so just do 3(-2) + 2 (Because you replace the number with the x) 3(-2) = -6 + 2 = -4!

I hope that helped!
