1. determine whether there is a minimum or maximum value to the quadractic function. find domain and range f (x) = - -x2-4x-9 4 2. use the vertex ( h, k) and a point on the (x, y) to find the general form of the equation of the quadratic (h,k) = (-2,5) (x, y) = (-3, - 1) 3. An athletic stadium holds 85,000 fans . with a ticket price of $ 14. the average attedance has been 33,000 when the prices dropped to $ 10.50 the average attendance rose to 43,500 assuming that attendance is lineary related to the ticket price, what ticket price would maximize revenue? 4. find the degree and leading cof fiecient for the given function if it is a polynomial g(x) =2(X3- 3) 3+ (X4-3) (X4+3) 5.
