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 + x + 12, y = −3x + 9
2.y = x2 − 4x − 1, y = −2x + 2
3.y = x2 − 5x − 2, y = −3x + 6
4.y = x2 − 8x − 1, y = −4x − 4
5.y = x2 − 4x, y = −3x + 6
6.y = x2 − 4x − 3, y = −x + 1
7.y = x2 − x + 12, y = −4x + 12
8.y = x2 − 3x + 4, y = −4x + 16
9.y = x2 + x + 18, y = −4x + 12
10.y = x2 + 2x + 16, y = −3x + 12
11.y = x2 − 11x, y = −4x − 12
12.y = x2 − x + 2, y = −2x + 4
