Enter different x-values into the equation and observe the behavior of the y-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 x-values can you enter into the equation?

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