A 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?
