At least 3600 students must attend to keep the cost per student at or below $44. The figure shows the graph of y = ax + bx + c. Suppose that the points ( - h,yo ) , (0,y1 ) , and (h,y2 ) are on the graph. (h, yz) The area enclosed by the parabola, the x-axis, and the lines x = - h and x = h may be given by the formula, Area = 2 (yo + 4y1 + y2) . Find the area enclosed by ( - h, yo )u (0 . 4 1 ) f(x) =x + 4x +7, the x-axis, and the lines x = - 4 and x = 4. The area is (Type an integer or a fraction.)
