Sketch a graph of the region bounded by the functions
How can you estimate the area in this region?
Graph the functions. Shade the region. Find all relevant intersections: Where does
intersect with ? Where does each function cross the -axis? How many integrals will you need?
The functions intersect at
. The area should be approximated with rectangles or trapezoids for and added to the area of the triangle for .
Using your method, estimate the area of the region.
