Step-by-step explanation:

6. Look at the graph of the equation x^2+y^2=8. Give its domain and range.

7. Use algebraic means to show that x^2+y^2=8 is not a function. Explain your process.

8. Is there any value(s) of the domain of x^2+y^2=8 that passes the vertical line test? If so, name the value(s) and state whether or not the existence of this value makes this relation a function. You can use Desmos to help you explore this idea, if needed.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
