Lesson Summary:
This video teaches viewers how to graph exponential functions with different modifications, such as a negative sign in front of the base or a shift in the exponent. The lesson walks through three examples and emphasizes the importance of being careful with computations, especially when dealing with negative numbers or fractions. Through practice, viewers can learn how to graph these variations of exponential functions accurately.

Staff Review
This lesson picks up where the last video left off and graphs some more exponential functions that are slightly more involved. The functions in this lesson involve more than just a number raised to an exponent. Now, numbers are added and subtracted from the function as well as from the exponent.
