A function is increasing on an interval if for any x1 and x2 in the interval then

            x1 <  x2          implies          f(x1)  <  f(x2)

A function is decreasing on an interval if for any x1 and x2 in the interval then

            x1 <  x2          implies          f(x1)  >  f(x2) @gigi_here ??
