Final Exam Review [5] (20 pts) A curve is defined by the equation x2 y2 - 20 = 4-4y. Find the equation of the tangent line at the point (2, -2). [9] (20 pts) Find the area enclosed by the graphs of y = 3 - x and y = x2 - 9. Express your answer as a rational number in lowest terms. [11] (20 pts) For the polynomial function (with domain all real numbers) f (2) = 23 - 322 +4 = (2+1)(20-2)2, find: x- and y- intercepts; intervals of increase / decrease and local extrema; the intervals on which the function is concave up and concave down. Use this information to sketch a graph of the function
