find the intervals on which the function is increasing, decreasing, or constant.
(7,2)(6,2)(5,2)(4,2)(3,2)(2,2)(1,2)(1,3)(3,4)(5,5)

Just check the slope on each interval.
increasing when slope > 0
constant when slope = 0
decreasing when slope < 0
Looks like it's constant at 2 for x in (7,1)
After that, it's increasing with slope = 1/2
