where f(x) is the top-function
So, figure out what function is above the other and get the anti derivative, then put in your limits
first find the intersection of the two functions in the given interval ...
finding the area will consist of two integrals because the "top" function changes ...
let
integrate and use the Fundamental Theorem of Calculus to find the area value.
note that this area problem is probably better suited for completion with a calculator.
