-The length of the cubes side is (x-5) and the total surface area is 1944 sq units.
-We apply the formula for surface area and equate to solve for x:

#Equate to zero as below:

length dimensions are always positive.
Hence, the value of x is 23

So f(x)=3
that means that whatever you input for x, you will always get 3
the graph is a horizontal line that goes through the point (0,3)
it is the same equation as y=3
R = -2 :) hope this helps
