46. Revenue, cost, and profit. The price-demand equation and the cost function for the production of HDTVS are given, respectively, by x = 9,000 – 30p and C(x) = 150,000 + 30x where x is the number of HDTVS that can be sold at a price of Sp per TV and C(x) is the total cost (in dollars) of produc- ing x TVs. (A) Express the price p as a function of the demand x, and find the domain of this function. (B) Find the marginal cost.

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
