Find lim x --> -2

Question

What is ?

Question options:

1)	−∞
2)	∞
3)	0
4)	−2

Answer 1

You are asked for the limit as x approaches -2, from the + side.

First, evaluate the expression at x = -2. The value is ∞. Next, evaluate at x = -1.99. the value is now -1.99/0.01 = -199. The limit approaching from the + side is therefor −∞
