Question

A function \[f\] is monotonic in an interval when it is which of the following?

पर्याय

• neither increasing nor decreasing in that interval

• strictly increasing and strictly decreasing in that interval

• constant only in that interval

• either increasing or decreasing in that interval

Answer 1

Monotonic means either increasing or decreasing on an interval. A function increasing on one interval and decreasing on another need not be monotonic on its entire domain.
