This document discusses finding the area between two curves, f(x) and g(x), on a calculator. It provides the formula for calculating the area between curves when f(x) is greater than or equal to g(x) over an interval [a,b]. It also gives an example of finding the area between the curves f(x)=4x-x^2 and g(x)=5-2x.

1. Find the derivative of this function:

2. Finding Area Between Curves
Find the total area enclosed between the graph of ƒ( ) and the x-axis.

3. Another way of doing this would be:
How would we do this on a calculator?

4. Area of a Region Between Two Curves
If f and g are continuous functions and f(x) ≥ g(x) for all x in the
interval [a, b], then the area of the region between the graphs of f
and g from x = a to x=b is

5. Finding the area between two curves, ƒ and
f(x) = 4x - x2 g(x) = 5 - 2x
