murphie, this graph may help you visualize the graph .. . .

I'm confused, the graph from my calculator looks completely different, your graph suggests that the left behavior at y=-4 is - infinity, and - infinity on the right?? and for the asymptote at y=4 the left is - infinity and right is infinity?
I am fairly bad at calculus so feel free to correct me if i said something stupid. But thanks for your help.

your equation can be re-arranged into this,
y = (3 - x)/((x - 4)(x + 4)), that means x = -4 and x = 4 are vertical asymptotes.
y approaches zero as x approaches positive or negative infinity
