Question

A parabola, with its vertex at the origin, has a directrix at y = 3. which statements about the parabola are true? select two options.

Answers

  1. The correct options about parabola are:
    The focus is located at (0,–3).
    The parabola can be represented by the equation x^2 = –12y.
    According to the statement
    we have given that the vertex is at the origin and directrix at y = 3.
    and from these given information and we have to find the all abot the parabola like its focus point etc.
    So,
    We know that the equation of parabola is
    (x-h)^2 = 4p(y-k)
    Here The vertex is (h,k). and the focus is at (h,k+p). and the directrix is   y(k – p.)
    So, From the given information
    Vertex at the origin means that h=0 and k=0
    Directrix at y = 3 means that p=-3
    Directrix at the y-axis means the parabola opens upwards.
    Thus, the focus is: (0,-3)
    And The p-value becomes
    : 4(-3) = -12.
    And from all these the equation of the parabola is becomes
    (x)^2 = -12y
    So, The correct options about parabola are:
    The focus is located at (0,–3).
    The parabola can be represented by the equation x^2 = –12y.
