Question

A hyperbolic mirror can be used to take panoramic photographs. A camera is pointed toward the vertex of the mirror and is positioned so that the lens is at one focus of the mirror. An equation for the section of the mirror is \[(\frac{ y^{2} }{4^{2}}) - (\frac{ x ^{2} }{ 3^{2} })\] where x and y are measured in inches. How far is form the mirror is the lens? With illustration please.
