(Section 1.2: Graphs of Functions) 1.2.13 PART H: INTERVALS OF INCREASE, DECREASE, AND CONSTANT VALUE We may have an intuitive sense of what it means for a function to increase (respectively, decrease , or stay constant ) on an interval. In Examples 11 and 12, we will formalize this intuition. Example 11 (Intervals of Increase and Intervals of Decrease from a Graph) Let fx () = x 3 ± 3 x + 2 . The graph of f is below. Give the intervals of increase and the intervals of decrease for f . • It is assumed that we give the “largest” intervals in the sense that no interval we give is a proper subset of another appropriate interval.
