Find the open intervals on which the function f(x) = −11x² + 10x + 8 is increasing or decreasing. Note: Use the letter U for union. To enter oo, type the word infinity. If the function is never increasing or decreasing, enter NA in the associated response area. increasing: decreasing: Find the local maximum and minimum values of the function f(x) = −11x2 + 10x + 8. Enter your answers in increasing order. • If there is just one local maximum or minimum value, then in the second row below enter NA as answer for "x =" and select NA in the "there is" drop-down menu. • If there are no local maximum or minimum values, then in both rows below enter NA as the answer fo x =" and NA in the "there is" drop-down menu. At x = ab P, there is At x = sin (a) b sin (a) ∞ Click for List ∞ a α 110 E 110
