Best ResponseYou've already chosen the best response.0The graph of a function can never cut the yaxis in two places. As this contans y to the powewr 2 it implies that the graph will cut in two places the yaxis. Hence not a function.

Best ResponseYou've already chosen the best response.1it can cut the y axis twice; there is no reason to suggest that y is not the input and x the output; it is only by convention that x is left and right, while y is up and down

Best ResponseYou've already chosen the best response.0I take your point, it is a little pedantic but the conventions of xaxis and yaxis as we both understand them allows my answer to hold.
