In your early studies of algebra, you learned how to find the equation for a line of best fit and analyze the strength of the fit using the correlation coefficient and residuals.  You expanded your understanding of modeling data to the exponential and quadratic function families.  In this lesson, you will be introduced to other function families that may be appropriate models for data.

Algebra II Journal: Reflection 1

Before exploring these function families, let’s review what we know about linear, quadratic and exponential models.  Complete the graphic organizer in your Algebra II Journal opens in new window (a copy is shown below), and submit it to your teacher.
