曲线之间的面积练习
曲线之间的面积 · 1–12
求两条曲线围成的区域的面积。
1.y = x2 − 4x + 21, y = 3x + 9
3.y = x2 − 5x + 18, y = 2x + 6
4.y = x2 + 5x − 6, y = 3x − 6
6.y = x2 + x − 18, y = 2x − 6
7.y = x2 − 21, y = 2x − 6
8.y = x2 − 3x + 10, y = 2x + 4
9.y = x2 + 4x − 9, y = 2x − 6
10.y = x2 + 2x − 24, y = 2x − 8
11.y = x2 + 8x + 8, y = x − 4
12.y = x2 + 3x − 6, y = x − 3
