    Consider the functions and . 2-125 HW eTool (Desmos). Homework Help ✎

  1. Verify that they are equivalent by creating a table or graph for each function.

    Here are a couple of points on the table. Make sure you get these points and continue both of your tables for at least the -values given.

  2. Show algebraically that these two functions are equivalent by starting with one form and showing how to get the other.




  3. Notice that the value for is in both forms of the function, but that the values for and are different from the values for and . Why is the value for the same in both forms of the function?

    What does the value for a represent?

Use the eTool below to graph the equations.
