Question

Algebra 2! Medal :D

Answer 1

Do you know much about parabolas?

Answer 2

yah but not when it comes to directrix

Answer 3

@paki @mathmate

Answer 4

Ok, I got you if you need help. I love these things.

Answer 5

ok yes please haha

Answer 6

The standard equation for a parabola of this type is \[(x-h)^{2}=4py\] This is because the vertex is off center and it is a parabola that opens upwards.

Answer 7

Ok, first things first here. Let's draw this out so far.

Answer 8

Do you know where the vertex lies in regards to the focus and the directrix?

Answer 9

Do you know what the line of symmetry is?

Answer 10

yah its the line straight down in the middle of the paraabola

Answer 11

@IMStuck

Answer 12

Right. So the line of symmetry is at x = 5. Do you know where the vertex is then? It lies directly between the focus and the directrix. The focus is at (5, -1) and the directrix is y = 1. Where is the vertex?

Answer 13

wouldn't it be at 0 then
