Option a is not a function because for x = 0, y = 3 and 4.
option b is a function.
option c is not a function because for x = 2, y = 1 and 8.
option d is not a function because for x = 1, y = -3 and 4
I believe it's -2 but i'm not 100% sure.

Answer:
3) x = 9
4) x = 3
Step-by-step explanation:
3) The two short segments are indicated as having a sum equal to the long segment.
(x +2) +(-5 +x) = 15
2x = 18 . . . . . . . . . . . . add 3
x = 9 . . . . . . . . . divide by 2
(This makes the segments be 9+2 = 11 and -5+9 = 4, which total 15.)

4) Same deal.
3x +3 = 4x
3 = x . . . . . . . . subtract 3x
(This makes the segments be 3(3) = 9 and 4(3) = 12, where 9+3=12.)
