do you know what it looks like approximately?
OpenStudy (katherinesmith):
not at all.

vertex is at the origin \((0,0)\) and focus is at \((0,6)\)which is 6 units up
we need to know what it looks like so we know that the \(x\) term is squared, i.e. it the equation will look like
\[4py=x^2\]
OpenStudy (anonymous):
and in your case \(p=6\) so you get
\[24y=x^2\]
OpenStudy (katherinesmith):
now i have to break down the x^2 to be x =
OpenStudy (anonymous):
well no, there is no breaking down \(x^2\) whatever that means
you cannot write this as \(x=\text{ something }\)
OpenStudy (katherinesmith):
are you sure? okay.

i am sure
the \(x\) is squared, it is \(x^2\) not \(x\)
