Question

23. The equation y2 - x2 = 1 represents which conic section?hyperbolaellipsecircleparabola

Answer 1

The standard equation for a hyperbola with a vertical transverse axis is

`((y-k)^2)/(a^2)\text{ - }((x-h)^2)/(b^2)\text{ = 1}`

The centre is at (h,k)

Hence the equation

`y^2-x^{2^{}}=\text{ 1}`

Represents hyperbola.

Therefore the correct answer is Hyperbola
