## How do you find the equation of a parabola from a graph?

We can use the vertex form to find a parabola’s equation. The idea is to use the coordinates of its vertex (maximum point, or minimum point) to write its equation in the form y=a(x−h)2+k (assuming we can read the coordinates (h,k) from the graph) and then to find the value of the coefficient a.

## What is a hyperbola Class 10?

A hyperbola is the locus of all those points in a plane such that the difference in their distances from two fixed points in the plane is a constant. The fixed points are referred to as foci (F1 and F2 in the above figure) (singular focus).

## What is a hyperbola in maths?

hyperbola, two-branched open curve, a conic section, produced by the intersection of a circular cone and a plane that cuts both nappes (see cone) of the cone.

## What is A and B in hyperbola?

a represents the distance from the vertex to the center. b represents the distance perpendicular to the transverse axis from the vertex to the asymptote line(s).
