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
