The given function is increasing.
Consider negative values of x, -∞ ............-10, -9, -8........
The function is always increasing, for example, -10/(1+10) = -10/11 < -11/12 < -12/13 and so on.
For positive values of x, for example, 1/2 < 2/3 < 3/4 <......
Hence the function is increasing for all values of x.
