We can rewrite the double inequality x2yx as x2y and yx. These two inequalities define the region above the parabola y=x2 and the region below the line y=x.


 
The region x² ≤ y The region y ≤ x


The region which the inequalities both define is the region in the first quadrant that is bordered below by the parabola and above by the line.


The region x² ≤ y ≤ x
