Identifying hyperbola vertices and foci from y^2+2y=4x^2+3
Homework Statement Identify the type of conic section whose equation is given as y^2+2y=4x^2+3 Also find its vertices and foci (y-k)^2/a^2-(x-h)^2/b^2=1 Homework Equations I believe when you have x&y ^2 in an equation it can be either an ellipse or a hyperbola but if the signs are...- StudentofSci

Parabola with vertex (2,3) and vertical axis passing through (1,5)
Thank your reply. However, I do not think that equation is relevant to this problem. This being because the only information I am given is the vertex aside from that. The vertex is in the form (h,k). Other than that x is given to me if the "vertical axis" is actually the "vertically axis of...- StudentofSci
