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
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)
