Without using a graphing calculator,

let f(x) = x/(abs(x^2 - 9))

(a)Write an equation for each vertical asymptote for the graph of f.

(b)Write an equation for each horizontal asymptote for the graph of f.

(c) Is f odd, even, or neither? Justify your answer.

(d) Find all values of x for which f is discontinuous and classify each discontinuity as removable or non removable.

(e) Find the domain.

I can do a, b, d, and e after graphing, but graphing skills, without a calculator, are not my strong point.

C, I never understood it.

Thanks.
