Find the area of the region between the graphs of f(x) = 3x3 – x2 – 10x and g(x) = -x2 + 2x Again, set f(x) = g(x) to find their points of intersection. 3x3 – x2 – 10x = -x2 + 2x 3x3 – 12x = 0 3x(x2 – 4) = 0 x = 0, -2, 2 Note that the two graphs switch at the origin. Now, set up the two integrals and solve. Title. Find the area of the region in the ﬁrst quadrant enclosed by the graphs of x = y2 and x = y+2. Solution. The intersections of the two curves are easily determined: y2 = y+2) y2 y2 = 0) (y+1)(y2)=0) y = 1, 2. It is easy to sketch the region since one curve is a parabola and the other a straight line. Be able to nd the area between the graphs of two functions over an interval of interest. Know how to nd the area enclosed by two graphs which intersect. PRACTICE PROBLEMS: 1. Let Rbe the shaded region shown below. (a) Set up but do not evaluate an integral (or integrals) in terms of xthat represent(s) the area .
