Question

i need help finding parabolas the vertex, directrix, and focus
2) x=-1/12y squared
3)y= 1/4(x-2)squared
4) x-2=1/8(y+1)squared
5)y-2=-1/16(x-1)squared
also need help graphing ellipses
3) (x-7)squared/4+(y-3)squared/9=1
4)(x-3)squared/4+(y+3)squared/16=1
5)(x-2)squared/1+(y-1)squared/4=1
6)x squared/25+(y-2)squared/9=1

Answer 1

Do you mean that it is x^2=-1/12y for the first part?

Answer 2

You'll find this page:

has a good explanation for finding the vertex, directrix, and focus.

Answer 3

HI!!

Answer 4

that is a lot of questions
which one do you want to do, and do you want to do it the slow way or the fast way?
