Hello?

anonymous · Answer

Please help, I need to know how to do this, I am working alone online - my teacher won't help and the lesson doesn't make sense. Please help.

anonymous · Answer

@phi can you help?

phi · Answer

First,  plot the focus and vertex
(roughly , need not be a work of art)
can you do that?

anonymous · Answer

sure hold on

anonymous · Answer

actually no, can you? not sure where everything goes

phi · Answer

vertex is (0,0) and focus is (0,-7)
can you plot these points?

anonymous · Answer

yep|dw:1437595113760:dw|

phi · Answer

and the parabola is a U shape the "curls around" the focus
the vertex is the "tip" of the parabola.  
so it looks like this
