Je xvin x 29. Find the area between the curves y = x and y = 3x - x2 by first identifying the points of intersection and then integrating. 30. Determine the area contained between the curves y = 4 + 7 sin(x) and y = 4+ 27 -2x on the interval [, 3"]. (Hint: Is one curve always on top of the other on this interval?) 2
