Aparabola has a vertex at the origin. the equation of the directrix of the parabola is y = 3.
what are the coordinates of its focus?
(0,3)
(3,0)
(0,–3)
(–3,0)
urgent. need quick.

The correct option is 3.

Step-by-step explanation:

The vertex of parabola is origin and directrix of the parabola is y = 3.

The standard form of a parabola is

Where (h,k) is vertex. (h,k+p) is focus and y=k-p is directix.

The vertex of parabola is origin. So,

Directrix of the parabola is y = 3.

The value of p is -3.

Focus of the parabola is (h,k+p).

Therefore focus of the parabola is (0,-3) and option 3 is correct.

hi there, the correct answer would be c! or (0,-3) hope this helps :)

Step-by-step explanation: i just took the test and got all of em correct

lol we need to see what the question is asking about

step-by-step explanation:

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
