Question

Find the standard form of the equation of the parabola with a focus at (7, 0) and a directrix at x = -7.

Answer 1

.y =1/28 x2

x = 1/28 y2

-28y = x2

y2 = 14x

Answer 2

x = 1/28 y2

Answer 3

Find the standard form of the equation of the parabola with a focus at (0, 2) and a directrix at y = -2.

y2 = 2x

y = 1/2 x2

y2 = 8x

y =1/8 x2

Answer 4

y =1/8 x2

Answer 5

Find the standard form of the equation of the parabola with a vertex at the origin and a focus at (0, 9).

y =1/36 x2

y =1/9 x2

y2 = 9x

y2 = 36x

for Q5 its second option

Answer 11

for Q6 let the eq of parabola be x^2=-k y

now substiute (14,-74) or (-14,-74) to find k and then use the eq for ur question
