Question

Evaluate the function at x = –2




  A. y = –2
  B. y = 0
  C. y = 2
  D. y = 3

Answer 1

The answer is equal C, y = 2.

Answer 2

- - C.

I have attached a picture explaining what I mean.
As you can see the line reached a point (on x=-2) and the answer is C.2 (Positive because it is on the higher end no the lower end.
