It won't let me open up the link what's the question

pflori1234_pop · Answer

It say "Graph the parabola. Identify the vertex focus and directrix.
$$-2x^2=16y$$

mrs.ambrose614 · Answer

Are you sure it says directrix????

pflori1234_pop · Answer

yes

mrs.ambrose614 · Answer

The directrix is y=2 the vertex is y=x2/8

mrs.ambrose614 · Answer

Feel free to give me a medal if I awnsered your question plz

The app you can use to find all of your awnsers is called math way it shows you everything from graphs algebra trigonometry and so much more and it's free to download and use

You have the following equation$$-2x^2=16y$$

mathmale · Answer

Please write it in the form y=4px^2.  Can you determine the value of "p" through doing this?

Can you identify the coordinates of the vertex of this parabolic graph?

The focus is |p| units from the vertex along the vertical axis, and the directrix is the same distance, but in the other direction along the vertical axis.

Find p, and then find |p|.

Your focus is at (0,p) and your directrix has the equation y=p.  Note that "p" is negative in this particular problem.
