This exponential functions introduction explains what an exponential function is and graphing exponential functions using a table of values. We talk about what numbers we are allowed to use as a base for exponential functions and practice plotting points to sketch the graph of a function. In this introduction to exponential functions, we look at patterns of graphs with different bases and introduces the fact that the graphs of exponential functions have horizontal asymptotes. This is a topic commonly found in an algebra or precalculus course.
