SECTION 2.1: INCREASING, DECREASING, AND PIECEWISE FUNCTIONS; APPLICATIONS | |
Increasing, Decreasing, and Constant Functions A function f is said to be increasing on an open interval I if for all a and b in that interval, $a<b$ implies $f(a)<f(b)$. A function f is said to be decreasing on an open interval I if for all a and b in that interval, $a<b$ implies $f(a)>f(b)$. A function f is said to be constant on an open interval I if for all a and b in that interval, $f(a)=f(b)$. |
Determine the intervals on which the function is (a) increasing; (b) decreasing; (c) constant. |
