Answer
a) Cannot be determined or, $\text{Indeterminate}$
b) $\infty$
c) $\infty$
Work Step by Step
a)$\lim\limits_{x \to a} [f(x)p(x)] = 0(\infty)=$ $\text{Indeterminate}$
b) $\lim\limits_{x \to a} [h(x)p(x)] =$
$\lim\limits_{x \to a} h(x) \times \lim\limits_{x \to a} p(x) = 1 ( \infty) = \infty$
c) $\lim\limits_{x \to a} [p(x)q(x)] =(\lim\limits_{x \to a} p(x))( \lim\limits_{x \to a} q(x)) = (\infty )(\infty) = \infty$
