In this lesson, the definition of exponential functions is explored and three different exponential functions are graphed. An exponential function is of the form f(x) = b^x where b is greater than zero and not equal to one. The graph of the function changes depending on the value of b, with some exponential functions being steeper than others. The lesson also covers the fact that the same exponential function can be written in different ways, giving students a more comprehensive understanding of exponential functions.
In this video, exponential functions are defined and graphed.
