You'll find it a lot easier to work on OpenStudy on a computer (rather than on a mobile device).  But it's your choice!

Find the (positive) distance between the vertex and the focus of this parabola.  You might want to draw a graph showing the locations of both.

Have you seen this form of the equation of a parabola before?  If so, where does the " p " come from?

$$4p(x-h)=(y-k)^2$$
