check the picture below.
so the area of the rectangle is x*y.
the area of the triangle is (1/2)(w)(z).
if we subtract the area of the triangle, from the containing rectangle, we're in effect making a whole in the rectangle, as you see there in lower-right corner.
I would start by using completing the square to rewrite the function 'y' in vertex form:
Now since you want the inverse, swap the x,y variables
Make a substitution to introduce parameter 't'.
Therefore
The rule says that the sum of any two sides has to be smaller than the third side so, no it can't
