LEARNING OBJECTIVES
- Understand nonlinear relationships and how they are illustrated with nonlinear curves.
- Explain how to estimate the slope at any point on a nonlinear curve.
- Explain how graphs without numbers can be used to understand the nature of relationships between two variables.
In this section we will extend our analysis of graphs in two ways: first, we will explore the nature of nonlinear relationships; then we will have a look at graphs drawn without numbers.
