Identifying Intervals Where a Graph is Concave Up By Examining the Graph | Calculus | Study.com

Identify the open intervals on which the graph of the function is increasing or decreasing. Assume that the graph extends past what is shown. 100 80- 60+ 40- 20 10 8 6 4 2 0 20- 40- 60 80- 100- Note: Use the letter U for union. To enter ?, type infinity. 2 4 6 8 10 Enter your answers to the nearest integer. If the function is never increasing or decreasing, enter NA in the associated response area. increasing: decreasing:
