    d) The equation of the standard parabola

    x² = 6 y

    Step-by-step explanation:

    The given directrix is y = - 31.5

    The equation of the parabola is of the form x² = 4 a y

    Given focus (0,1.5), Here a = 1.5

    The equation of the standard parabola

    x² = 4 a y

    x² = 4 (1.5) y

    x² = 6 y

    Conclusion:-

    The equation of the standard parabola

    x² = 6 y
