# How do you graph y > 2x^2 − 3  and y < -x^2+8?

Oct 3, 2015

Graph and solve the system
y > 2x^2 - 3 (1)
y < -x^2 + 8 (2)

#### Explanation:

First, graph the parabola y1 = 2x^2 - 3.
The solution set of inequality (1) is the area above the parabola y1. Color or shade it.
Next, graph the parabola y2 = - x^2 + 8.
The solution set of inequality (2) is the area below the parabola y2.
The compound solution set is the commonly shared area.
