Students will learn how to solve and graph polynomial inequalities using a sign chart.
Concude by giving your students this challenge:
Redblue by NRICH: When we ask students which solids have redblue vertices, what we're really asking is, when is a graph not bipartite? A graph is not bipartite if and only if it has odd cycles. So a solid has redblue vertices if and only if it has a face with an odd number of vertices.
