Hi.

dessyj1 · Answer

What do you mean when you say "focus"? Are you talking about the vertex, or the y-intercept?

k.binks · Answer

I don't really know, I had to graph the parabola y=1/32 x^2 and find the directrix and focus. I know the Directrix is 8 and someone told me the focus was (0,8) but if they hadn't, I wouldn't know how to find it or what it is on my own.

k.binks · Answer

they didnt explain, they just told me what it was (0,8)

dessyj1 · Answer

Yeah, I do not know how to do that. Maybe @triciaal can help?

another reason not to accept answers without understanding 
I was thinking   "doesn't this person know that the focus is just a point"

k.binks · Answer

No, I didn't know that, which is why I was asking someone to explain

dessyj1 · Answer

Sorry about that. She was talking to me.

The focus of a parabola is the point at the center of the parabola. all points on the parabola are the same distance from this point
