Is the graph increasing, decreasing, or constant?

Constant function.

Step-by-step explanation:

The graph shows a horizontal line, where clearly all values of the variable plotted on the vertical are the same (constant = -4) for all values of the horizontal coordinate. Since y doesn't change, we  refer to this function as a constant function.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
