Answer:

Step-by-step explanation:

A

y = 7 - x

y = 7 - 2

y = 5

B

y = x^2 - 1

y = (2)^2 - 1

y = 2*2 - 1

y = 4 - 1

y = 3

C

y = x + 14

I'm going to assume that you mean (x + 14)^3

y = (x + 14)^3

y = (2 + 14)^3

y = 16^3

y = 4096

If you really do mean what it says, then

y = 2 + 14^3

y = 2744 + 2

y = 2746

place 9 in the brackets

-3[1+2(9)]
