17. The profit P (in dollars) for a movie-rental machine is P(x) = -0.02x- +5x -110 , where x is the number of movies rented per day. What is the maximum profit per day and how many movies must be rented for the maximum profit? 18. Find a polynomial function of least degree with integer coefficients that has the following values as some of its zeros. You may leave your answer in factored form. a. x=3 X = A / W x = -5 C. x =-2+5i x=1 b. x =4+V3 x=0 19. Given the function f (x) = 3x' +17x' +12x-6, a. describe the end behavior b. list all possible rational zeros C. use the information in part b) to find all zeros of the polynomial function Solve the equation x* - 8x'+21x - 40x +80 =0. Find all zeros of the function and describe the end behavior given f (x) = x* - 4x2 -32. Find all zeros of the function given f (x) = x* -10x' + 34x - 42x +9. Find all zeros of the function given f (x) = 2x' +13x2 + 56x + 25
