Consider the function f(x) = 4x2 + 5x + 9. Find the largest open intervals on which the function is concave up or concave down. If there is more than one interval, enter your intervals from left to right as they appear on the real line. Enter INF for 00 and -INF for 00. If there are extra blanks, enter NONE. Concave up: (| |:| |):(| I: | l) TrisSW99 Concave down: (| |,| |),(| , | l) Find all the inflection points. Enter your answer in the format of (x, y) and enter the inflection point with the smaller x-value rst. If there are no inflection points, enter NONE.
