Question

Find f(5) and f(-1) for the equation:

Answer 1

Answer:

C. -8 and 4

Step-by-step explanation:

Step 1: Plug in f(5)

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

f(5) = -10 + 2

f(5) = -8

Step 2: Plug in f(-1)

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

f(-1) = 2 + 2

f(-1) = 4

Answer 2

Answer:

-8 and 4

Step-by-step explanation:

Put x as 5 and solve.

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

f(5) = -10 + 2

f(5) = -8

Put x as -1 and solve.

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

f(-1) = 2 +2

f(-1) = 4
