Question

Let
f(x) = 80 + 4x − 4x2
and
g(x) = 4x2 − 20x.
Sketch the region enclosed by the graphs of
f(x)
and
g(x)
and compute its area.

Answer 1

you will need to find the intersections of these 2 functions, that will be your limits
and then you need to graph them to see if it is f(x)-g(x) or g(x)-f(x)
