Make a complete graph of the function and describe its domain and range.   

Enter different -values into the equation and observe the behavior of the -values of the function, as well as the points on the graph.

Is the graph symmetric? What is the line of symmetry? Is there a highest point? A lowest?

For the domain, what possible -values can you enter into the equation?

What is the smallest -value? Is there a largest? What is the range?

Use the eTool below to make a complete graph of the function.
