3.the equation 3x^2-6y^2=6 represents which conic section?
4.write an equation for a parabola in which the set of all points in the plane are equidistant from the focus and line. F(-2,0); x=2
5.write an equation of a parabola that opens upward,has a vertex at the origin,and a focus at (0,1). Answer by solver91311(24713) (Show Source):
Please go back and re-read the instructions for posting on this site. In particular, pay careful attention to the instruction that says: "One question per post."
3. There is an term AND a term -- therefore NOT a parabola. The coefficient on the term is different than the coefficient on the term -- therefore NOT a circle. The sign on the term is different than the sign on the term -- therefore NOT an ellipse. Therefore it is a hyperbola.
