Don’t just calculate it please answer for the boxes will give brainliest if i can.

f(x) = 2x + 5

f(-1) = 2(-1) + 5

f(-1) = -2 + 5

f(-1) = 3

f(2) = 2(2) + 5

f(2) = 4 + 5

f(2) = 9

f(0) = 2(0) + 5

f(0) = 0 + 5

f(0) = 5

f(z) = 2(z) + 5

f(z) = 2z + 5

just keep asking questions until you have a better understanding.

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
