Question

Which equation describes a parabola that opens left or right and whose vertex is at the point (h, v)?

Answer 1

The correct answer is:

x = a(y-v)²+h

Step-by-step explanation:

Vertex form of a parabola differs depending on the direction the parabola opens. If it opens up or down, the equation is y = a(x-h)²+v, where (h, v) is the vertex.

If, however, the parabola opens left or right, the equation is x = a(y-v)²+h, where (h, v) is the vertex.

Answer 2

Vertex is at the point ( h , v )
The equation of a parabola is:
x = a ( y - v )² + h
