We can have discontinuous graph still satisfying decreasing function property..As basic definition is : f(x) is strictly increasing if f(a) > f(b) for all a < b. f(x) is increasing if f(a) >= f(b) for all a < b. rather than in terms of f'(x).. 0 votes 0 votes srestha commented Dec 29, 2016 reply Follow Share Without graph if any other way to derive it Like with function Can u give an example if example possible for f(a) > f(b) for all a < b. 0 votes 0 votes Please log in or register to add a comment.
