Graphing Square Root Functions Objectives SWBAT graph square root functions and calculate and interpret the average rate of change over an interval. (CCSS: F-IF. 7 b) DOL Given … SW graph square root functions and calculate and interpret the average rate of change over an interval with 80% accuracy. (CCSS: F-IF. 7 b) EQ: What other relationships can we model?

Function Families So far, we’ve learned how to model: �Linear functions When things grow or shrink at a constant rate over time �Exponential functions When things grow or shrink at a faster rate over time �Quadratic functions When things go up and come down �This unit we’re adding a few similar ones

Function Families We’ll learn to model �Square root functions �Cube root functions �Absolute value functions �Piecewise functions
