Which of the following statements best describes the location of a vertex ona parabola? a it's is located halfway between the parabolas focus and directrixb it is located on the parabola directixc it is located on the parabola focusd it is located halfway between the parabola two foci

Option A is correct that is it's is located halfway between the parabolas focus and directrix.

Step-by-step explanation:

We are given a parabola.

To find: Best statement which describes the location of the vertex on the parabola.

Standard Equation of Parabola which open on the Right hand direction.

( y - k )² = 4a( x - h )

Here, ( h , k ) is the vertex of the parabola and ( h + a , k ) is the focus.

Distance of the focus from vertex = a

Equation of the Directrix of the Parabola is , y =  k - a

Distance of the Directrix from vertex = a

Therefore, Option A is correct that is it's is located halfway between the parabolas focus and directrix.
