A print shop makes bumper stickers for election campaigns. If x stickers are ordered (where x < 10,000), then the price per sticker is 0.16 β 0.000002x dollars, and the total cost of producing the order is 0.091x β 0.0000005x2 dollars.Use the fact thatprofit = revenue β costto express P(x), the profit on an order of x stickers, as a difference of two functions of x.P(x) =Usef(x) = 3x β 4andg(x) = 6 β x2to evaluate the expression.(a) f(g(0)) (b) g(f(0)) f(x) = x β 4, g(x) = |x + 4|Find (f β g)(x). Find the domain of (f β g)(x). (Enter your answer using interval notation.) Find (g β f)(x). Find the domain of (g β f)(x). (Enter your answer using interval notation.) Find (f β f)(x).
