20 POINTS PLZ HELPA company produces remote-controlled helicopters. The company’s profit, in thousands of dollars, as a function of the number of helicopters produced per week can be modeled by a quadratic function. When 1 helicopter is produced per week, the company’s profit is 4 thousand dollars. The maximum profit, 22 thousand dollars, occurs when 4 helicopters are produced per week. If h is the number of helicopters produced per week, which function models the scenario?f(h) = –4(h – 1)^2 + 4f(h) = –2(h – 4)^2 + 22f(h) = (h – 4)^2 + 22f(h) = (h – 1)^2 + 4
