I am supposed to write the standard equation of the parabola with the directrix x=1, and the vertex 6,2. I got y-6=1/4p(x-2)^2. Is this correct? I am supposed to graph y+3=-1/12(x-1)^2. I tried to find p, and I got 36. I don't think this could be correct,...

(I posted this yesterday, if it looks familar, but no one was on who could help me). I am supposed to graph y+3=-1/12(x-1)^2. How do I find the equation of the directrix, and the coordinates of the vertex and the focus?

My standard-form equation is (x+3)^2+(y+2)^2=4. Do I find the radius by doing the square root of four? I just wanted to check on this. Based on the example in my book, it seemed like this is the way to do this, but I wanted to make sure, because they didn...

Thanks to those who helped with my question: y+3=-1/12(x-1)^2. The only thing I am still unsure of is how to write the equation for the directrix. Do I just simply write 0=3-3, (the values plugged in for y=k-p). Thanks again for your help!!
