Evaluate f (x) = 3x – 5 when x = -1, x = 0, and x = 3.

f(x) = 3x − 5 when x=−1, x=0, x=3

-8, -2, 4

Step-by-step explanation:

1. Insert -1, 0, and 3 into x

2. Solve

Replace x with -1: f(-1) = 3(-1) − 5

Multiply 3(-1): f(-1) = -3 − 5

Subtract by 5: f(-1) = -8

The answer is -8

Now do this for the rest of the problems:

f(0) = 3(0) − 5 when x=−1, x=0, and x=3

-2 is the 2nd answer

f(3) = 3(3) − 5 when x=−1, x=0, and x=3

4 is the 3rd answer

-8,-5,4

Step-by-step explanation:

If x=-1 then f(-1)=3(-1)-5,the answer would be-8

If x=0 then f(0)=3(0)-5,the answer would be -5

If x=3 then f(3)=3(3)-5,the answer would be 4
