Let's say that h(x) = x+3. To find the inverse switch h(x) and x and call h(x) by its inverse name

. so f(x) = x - 3.
so h(f(x)) = (x - 3) + 3 = x what we did is plug f(x) in for x which is the inverse of h(x). The answer is h(f(x)) =x.

Determine the 4th point
The coordinate point of a horizontal or a vertical rectangle is given as:
(x1,y1), (x2,y2), (x3,y3), (x4,y4)
Where:

So, we have:
--- 
---- 
---- 
Using the above equations:


Hence, the coordinate of the 4th point is:
