You can put this solution on YOUR website! What are the points of discontinuity, holes, vertical asymptotes,x-intercept, and horizontal asymptote of the problem
f(x)= (x^2+x-6) / (-4x^2-16x-12)
---
Factored Form:
f(x) = [(x+3)(x-2)] / [-4(x+3)(x+1)]
------------------------------------
Pts of discontinuity: x = -3 and x = -1
-----------------------------
holds: x = -3 because (x+3) is a factor of numerator and denominator
---------------------------------
vertical asymptote at x = -1
-----------------------------------
horizontal asymptote = x^2/-4x^2 = -1/4
-----------------------------------
x-intercept:
Let y = 0 ; solve for "x"
x = 2
