X and y intercepts?

Horizontal Asymptotes?

Vertical Asymptotes?

**Damon**, Friday, February 21, 2014 at 11:20amy = (x-1)(x+2) / [ (x-4)(x+1)]

when x = +1 , y = 0

when x = -2 , y = 0

when x = 0 , y = -2/-4 = 1/2

vertical when x = 4 or x = -1

= x^2/x^2 --> 1 when x is big positive or big negative

this:

(x^2+x-2) / (x^2-3x-4)
