Question 434871: This is what I have and I did something wrong. Any help would be appreciated. It wouldn't let me put my graph on here, but I have the points displayed.
f(x)=-2/(x^2+2x-3)
=(x+3)(x-1)
x=-3 or x=1

-------------------------------------
Adjusted Answer:
f(x)=-2/(x^2+2x-3)
--
Factor the denominator:
f(x) = -2/[(x+3)(x-1)]
---
The graph will have vertical asymptotes at x = -3 and at x = 1.
---------------------------------------------
Points:
If x = -5, y = -2/[-2*-6] = -1/6
If x = 0, y = -2/[3*-1] = 2/3
If x = 2, y = -2/[5*1] = -2/5
