Unit 6, Lesson 5# Increasing and Decreasing Functions (Continued)

EngageNY 45 min(s)

Students qualitatively describe the functional relationship between two types of quantities by analyzing a graph. Students sketch a graph that exhibits the qualitative features of linear and nonlinear functions based on a verbal description. Students begin the lesson by comparing and contrasting linear and nonlinear functions. Encourage students to distinguish a linear function from a nonlinear function by analyzing a graph using the rate of change for an interval instead of just stating that "it looks like a straight line."
