While warming up for a game, two basketball players shoot balls in parabolic paths. The path of the first player's ball can be represented by the function glx)=-2x + 13x+7, where x represents the distance from the coach. The path of the second player's ball can be represented by the function h(x)=-x2+4x+21. Part A: Find the distances in which the two basketball paths will cross. Show all necessary calculations. (4 points) Part B: Let f (x)=9(x) bix Solve for f (x) in simplest form and determine all discontinuities. (6 points)
