The absolute maximum and minimum values ...

The absolute maximum and minimum values of function can be found by their monotonic or minimum . For instance , the absolute maximum value of `(1)/(1+x^(2))` is unity . It is attained at x=0 while absolute minimum value of the same function is zero which is a limiting value of `(xtoooor xto-oo)`
