This lesson unit is intended to help teachers assess how well students are able to interpret exponential and linear functions and in particular to identify and help students who have the following difficulties: translating between descriptive, algebraic and tabular data, and graphical representation of the functions; recognizing how, and why, a quantity changes per unit intervale; and to achieve these goals students work on simple and compound interest problems.

This assessment will check for understanding of goals NC.M4.AF.3.1, NC.MA.AF.3.2 and NC.MA.AF.3.3.  This is an open-ended assessment that includes changing from expnential to logarithmic form, properties of logarithms, solving logarithmic and exponential equations and applications with exponential and logarithmic functions.
