# Math Help - find the domain

1. ## find the domain

Can someone tell me if I am right with this answer:

Find the domain of the function f(x)=x^4/(x^2+x-6)

I think it should be "all x not equal to 2 or -3" because that would make the denominator 0...is this right?

Yes.

This can be written $\mathbb{R} \backslash \{-3,~2\}$ or $(-\infty,~-3) \cup (-3,~2) \cup (2,~+\infty)$

3. Yeah! Finally I got one right! Thanks for your help!!!!
