BMIT HAND WRITTEN SOLUTIONS TO BLACKBOARD Consider the function below. f(x) =18 - 24x + 9x2 - 23 On what set of numbers is the function increasing? (Use interval notation) On what set of numbers is the function decreasing? (Use interval notation) For what x-coordinate does the graph y = f() have a relative maximum? At what x-coordinate does the graph y = f(x) have a relative minimum? C On what set of numbers is the function concave-up? (Use interval notation) On what set if numbers is the function concave-down? (Use interval notation) A what x-coordinate does the graph of y - f(x) have a point-of-inflection? ac Please sketch a graph of the function. Label all relative extremes and POI
