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 x-values given.
Show algebraically that these two equations are equivalent by starting with one form and showing how to get the other.
Notice that the value for a is 3 in both forms of the equation, but that the numbers for b and c are different from the numbers for h and k. Why do you think the value for a would be the same number in both forms of the equation?
What does the value for a represent?
Use the eTool below to graph the equations.
