Question
Which equation describes a parabola that opens left or right and whose vertex is at the point (h, v)?A.y = a(x - v)2 + hB.y = a(x - h)2 + vC.x = a(y - v)2 + hD.x = a(y - h)2 + vSUBMITarrow_backPREVIOUS
Solution
The equation that describes a parabola that opens left or right and whose vertex is at the point (h, v) is D. x = a(y - h)² + v. This is because when the x is the subject of the formula, it means the parabola opens to the left or right. The (h, v) in the equation represents the vertex of the parabola.
