Find the standard form of the equation of the parabola with a focus at (0, 3) and a directrix at y = 3.
y2 = 12x
y2 = 3x
y = negative 1 divided by 12x2
y = negative 1 divided by 3x2

Best ResponseYou've already chosen the best response.0Find an equation in standard form for the hyperbola with vertices at (0, ±6) and asymptotes at y = ±3 divided by 2.x. y squared over 36 minus x squared over 16 = 1 y squared over 4 minus x squared over 9 = 1 y squared over 36 minus x squared over 4 = 1 y squared over 16 minus x squared over 36 = 1
