Show all analytic work. Graphs can be done by hand. There is a total of 110 points. 1. y= /(x) = 2x' -3x -72x,-5x$5. a) (4 pts) Find the (x, y) coordinates of the critical points. b) (4 pts) Find the (x, y) coordinates of the point of inflection. c) (4 pts) Use the test for concavity and determine over what interval the curve is concave up and where is it concave down? d) (4 pts) Check the (x, y) coordinates of the end points and find all absolute max and absolute min points. Also graph the curve and label the inflection point and critical points
