Mark the correct alternative in the following:
Let f(x) = tan–1 (g(x)), where g(x) is monotonically increasing for Then, f(x) is
Formula:-
(i)The necessary and sufficient condition for differentiable function defined on (a,b) to be strictly increasing on (a,b) is that f’(x)>0 for all x(a,b)
Given:- f(x) = tan–1 (g(x))
For increasing function
f’(x)>0
