Let f( x) = = 8X x2 + 9 Use a graphing utility to graph y = f(x). y 2 - X -6 2 4 -6 -4 -2 2 4 -2 -2 -2 -4 -61 -6 O O 2 2 - x - X -6 -4 -2 2 4 -6 -4 - 2 2 4 6 -2/ -2 -4 -4 From the graph, approximate the intervals over which fis increasing. (Enter your answer using interval notation.) List the intervals over which f is decreasing. (Enter your answer using interval notation.)List the local maximums, if any exist. (If an answer does not exist, enter DNE.) (x, V ) = List the local minimums, if any exist. (If an answer does not exist, enter DNE.) (x, V) = Approximate the range of f. (Enter your answer using interval notation.)
