Graphing and Analyzing Inequalities

The video tutorial explains how to graph the solution to a system of inequalities. It covers graphing a quadratic inequality, y < x^2 - 6, using a dashed parabola and determining the shaded region. It also explains graphing a linear inequality, y >= -1/4x + 3, using a solid line and identifying the shaded region. The solution to the system is the double shaded region, which is unbounded.

What is the solution to a system of inequalities?

• The region below both graphs

• The region where the graphs do not overlap

• The region above both graphs

• The region where the graphs overlap
