Solving and Graphing Polynomial and Rational Inequalities

The video tutorial covers graphing and solving inequalities, including polynomial and rational inequalities. It begins with a basic introduction to inequalities, explaining the difference between equations and inequalities. The tutorial then demonstrates how to solve polynomial inequalities using number lines and test points. It also covers graphing two-variable inequalities by treating them as equations and shading the solution area. Finally, the video explains rational inequalities, focusing on finding x-intercepts and vertical asymptotes. The tutorial concludes with a comprehension check.
