2. Solving Quadratic Equations by Graphing
Sign In
Each point that lies inside the shaded region is a solution of the quadratic inequality.
Sometimes
Let's analyze the given graph of a quadratic inequality.
Each point that lies inside the shaded region is a solution of the quadratic inequality.
We want to determine whether the y-value of a solution of the inequality is sometimes, always, or never greater than 2. First, let's draw the line y=2.
We can take note of the following observations.
We can find points that lie inside the shaded region, and have different position with respect to the line y=2.
Therefore, sometimes the y-value of a solution is greater than 2.
