In this chapter, we shall study the nature of a function which is governed by the sign of its derivative. If the graph of a function is in upward going direction or in downward coming direction then it is called as monotonic function, and this property of the function is called monotonicity. If a function is defined in any interval, and if in some part of the interval, graph moves upwards and in the remaining part moves downward then function is not monotonic in that interval.
There are two types of monotonic function.
A function f(x) defined in a domain D is said to be monotonic increasing function if the value of f(x) does not decrease (increase) ...
