Consider the equations and . 2-24 HW eTool (Desmos)  Homework Help ✎

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

    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 equations 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 equation, but that the numbers for and are different from the numbers for  and . Why do you think the value for would be the same number in both forms of the equation?

    What does the value for represent?

Use the eTool below to graph the equations.
