Given the rational function f(x) = 2x^3 - 7x + 3 / x^2 - 4

a) Determine all of the asymptotes of f(x). Explain your work clearly.

b) Make a neat sketch of f(x). Label all important parts.

I determined that the vertical asymptotes are x = -2, 2 (hopefully I'm right), and there are no horizontal asymptotes. I'm wondering if there is a slant asymptote? How can I tell? If there is one how do I find what the slant asymptote is?

How would the graph look like?

Thanks for your time.
