Find the standard form of the equation of the parabola with a vertex at the origin and a focus at (0, -7).
y = negative one divided by seven x^2
y^2 = -7x
y = negative one divided by twenty eight x^2
y^2 = -28x

Answer :

Answer:

c) y = negative one divided by twenty eight x²

  Equation of the standard parabola  x² = -28 y

Step-by-step explanation:

Explanation:-

Given vertex of the parabola (0,0)

Given Focus is ( 0, -7)

The standard parabola is x² = -  4 a y

Given Focus is ( 0, - a) = ( 0, -7) here focus a =7

                              x² = -  4 a y

                              x² = -4(7)y

                              x² = -28 y

Conclusion:-

Equation of the standard parabola  x² = -28 y
