Individually, the inequalities \displaystyle y\ge x^{2} and \displaystyle y\le 1 define the region above the parabola \displaystyle y=x^{2} and under the line \displaystyle y=1, respectively.

The region y ≥ x²		The region y ≤ 1

Those points which satisfy both inequalities lie in the region above the parabola, but below the line \displaystyle y=1\,.
