The function xe^x is increasing in

f(x)={(0,quad x=0),(x-3,x>0) :} .The function f(x) is (a) Increasing when x>=0 (b) Strictly increasing when x>0 (c) Strictly increasing at x=0 (d) Not continuous at x=0 and so it is not increasing when x>0

The function (log x) /x is increasing in

The function f(x) = x^2 is increasing in the interval

The function sin x-cos x is increasing in

The function log (log x) in increasing in

Prove that the function x - cos x is increasing on R.

the function f(x)=logx/x is increasing in the interval
