You will learn how to visually identify information about the system of equations simply by examining the graphs of the lines that make up the system.StandardsCC.2.2.HS.D.10Represent, solve, and interpret equations/inequalities and systems of equations/inequalities algebraically and graphically.

This seminar will teach you how to identify the graph of an exponential function. You will learn how to identify the properties of the function that explain the shape of the graph. The seminar will also show you how to graph an exponential function that you are given. You will learn about the properties of the graphs of exponential functions and how they are related to the properties of exponents. You will be guided through examples of graphing using tables and also using properties of the functions themselves.StandardsCC.2.2.HS.D.7Create and graph equations or inequalities to describe numbers or relationships.
