The price p​ (in dollars) and the quantity x sold of a certain product satisfy the demand equation x x=−6p+300. Answer parts​ (a) through​ (g).

(b) What is the domain of​ R? Assume that R is nonnegative.

(a) The domain of the demand equation x = -6p + 300 is all real numbers for both x and p.

(b) The domain of R is all nonnegative real numbers, since price p and quantity x cannot be negative in a realistic scenario.
