4.The region of the xy plane that satisfies y > x^2 or y > 0 is
(A) a circle
(B) a square
(C) the region of the plane bounded by a parabola

(E) the half of the plane above the x-axis
请说明为什么.

在xy平面内满足 y 大于x的2次方 或 y大于0 的是
A.一个圆
B.一个矩形
C.平面区间附近的一条抛物线
D.平面内一个新月型的区域
E.x轴上方一半的平面(要是懂数学应该能理解,我也说不好)
翻译应该是这样吧..
题真的很简单,不过我数学一窍不通..- -#
y大于0应该就是x轴上面吧

。。。。。。。。。。。 完全看不懂……
