Use calculus to determine the area of the triangle give the verticies
(0,5) (2,-2) (5,-1)
recall that we find area of a bounded region by integrating the top function minus the bottom function. f(x) is always on top, but g(x) is the bottom function between x = 0 and x = 2. similarly, h(x) is the bottom function from 2 to 5. the points we were given are our guides.
