    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)
