3x^2+4y^2=121 is a Function, one-to-one, or neither?

Answer 1

The graph is an ellipse. Since the Vertical Line Test fails, we don't have a function. Since the horizontal Line Test also fails, one-to-oneness is not present.

Answer 2

I'd say 1:1 because when you use a value for "x"; "y" will have a certain value.
