Interpret Graphs of Functions
Videos and lessons to help Grade 8 students learn how to describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.
Common Core: 8.F.5
Suggested Learning Targets
- I can sketch a graph given a verbal description of its qualitative features.
- I can interpret the relationship between x and y values by analyzing a graph.
- I can analyze a graph and describe the functional relationship between two
quantities using the qualities of the graph.
