In this video, exponential functions are defined and graphed.
• What is the definition of an exponential function?
• How do you graph an exponential function using a table of values?
• How do you graph f(x) = 2^x?
• How do you graph y = 5^x?
• How do you graph y = (1/2)^x?
• What happens when 0 < b < 1 in y = b^x?
• What happens when b > 1 in y = b^x?
• What happens as b gets larger in y = b^x?
This lesson is a very good introduction to exponential functions. It explains what an exponential function is, gives the definition, and shows how to graph exponential functions. You will see how exponential functions and their graphs behave depending on the value of b in y = b^x.
