I just can't figure out this problem. I would like to know how I can figure it out more than just the answer. The x's need to be canceled out to figure it out but I can't think of how to do that without an equation.
If $\lim\limits_{x\to0} \frac{f(x)}{x^2} = 9$, evaluate the following limits:
(a) $\lim\limits_{x\to0} f(x)$.
(b) $\lim\limits_{x\to0} \frac{f(x)}x$
