**Reiny**, Monday, December 5, 2011 at 11:13pmcheck you typing.

did you mean

f(x) = (x^3 + 8)/(x^2 - 6)

or is it the way you typed it?

What is with the +-6 ?

**logan**, Monday, December 5, 2011 at 11:38pmit is f(x)=x^3+8/x^2+x-6

**Anonymous**, Tuesday, December 6, 2011 at 10:34amassuming you really do mean

(x^3 + 8)/(x^2 + x - 6)

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

It crosses the x-axis at x = -2

there are vertical asymptotes where the denominator is zero:

x = -3 or x=2

as x gets large, y -> x^3/x^2 = x
