`y=8/(x^2-x-6)` Graph the function.

We are asked to graph the function `y=(8)/(x^2-x-6) ` :


Factoring the denominator yields:


`y=8/((x-3)(x+2)) `


There are vertical asymptotes at x=-2 and x=3. Since the degree of the denominator is greater than the degree of the numerator, the horizontal asymptote is y=0.


The y-intercept is -4/3.
