QuestionThe price $p$ (in dollars) and the quantity $x$ sold of a certain product satisfy the demand equation $x=-6 p+300$. Answer parts (a) through ( g ). (a) Find a model that expresses the revenue R as a function of p . (Remember, $\mathrm{R}=\mathrm{xp}$.) $$R(p)=-6 p^{2}+300 p$$ (Simplify your answer. Use integers or decimals for any numbers in the expression.) (b) What is the domain of R ? Assume that R is nonnegative. A. The domain is $\{p \mid$ $\square$ $\leq \mathrm{p} \leq$ $\square$ (Simplify your answers. Type integers or decimals.) B. The domain is the set of all real numbers.
