- How to find f(-x)?

And also, would finding the asymptotes, slant asymptote, and point of discontinuity be easier if I simplify this rational first?:
(2x^3-3x^2-12x+20)/(x^2-5x+6)
I can simplify the denominator as (x+1)(x-6) but that's it...
Is the first step to simplifying the numerator... Factoring out x?
I'd appreciate any help, thanks so much!
