Question

Write the equation of a parabola with the focus at (3,0) and the directrix at x=-3

Answer 1

-12x=y  
y is squared  good luck

Answer 2

With a focus coordinate of a positive x and y = 0 this parabola opens towards the right .

the general form is y^2 = 4 ax    where (a,0) is the focus)    Here a = o

so the rquired equation is y^2 = 12x
