Mark the correct alternative in the following:
f(x) = 2x – tan–1 x – logis monotonically increasing when
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)
For increasing function f’(x)>0
