Question 282004
<font face="Garamond" size="+2">

If there is both a *[tex \Large y^2] term and an *[tex \Large x^2] term, then it is NOT a parabola.


If the sign on the *[tex \Large y^2] term is DIFFERENT than the sign on the *[tex \Large x^2] term, then you have a hyperbola,


Otherwise, you have a circle or an ellipse.  If the coefficient on the *[tex \Large y^2] term is equal to the coefficient on the *[tex \Large x^2] term, then it is a circle.


You have an ellipse.
