Im kinda new to the calculus thing but these questions have been really annoying me.

1.) Find any vertical, horizontal and oblique asymptotes of the function f(x) = (x^2-3)/(x-1)

2.) Let f(x) = x^3 + x^2 - 6x. Find the zeroes and use calculus methods to find the local max, min and inflection points of f(x) and sketch the graph of f(x)

Please help if you can
