**Steve**, Wednesday, December 19, 2012 at 4:32pmwhy what?

limit as x -> 1 from either side is

(-1-2)/(1-4) = -3/-3 = 1

one would expect this, as f is continuous.

**Steve**, Wednesday, December 19, 2012 at 4:35pmoops. I did x -> -1

limit as x -> 1 is

(1-2)/(1-4) = 1/3

Makes sense, since f(x) = 1/(x+2) for x ≠ ±2
