The graph represents the x^2+y^2=8. Use the graph to answer questions 6,7,8. 6. look at the graph of the equation x^2+y^2=8. give its domaim 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 verticle 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.
