Enclose arguments of functions in parentheses. For example, sin (2x). f( 4) (x) =Question 4: (6 points) Identify the open intervals on which the graph of the function is increasing or decreasing. Assume that the graph extends past what is shown. 107 8- 6+ 4- -10--8 .-6-4 12 0 2 4 - . 6 8 10 -2- 4- 6- 8- Note: Use the letter U for union. To enter oo, type infinity. Enter your answers to the nearest integer. If the function is never increasing or decreasing, enter NA in the associated response area. increasing: decreasing:Question 5: (7 points) Find the open intervals on which the function f (x) = -3x- + 2x + 1 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) = -3x2 + 2x + 1. 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 the answer for "
