Question

Hi, can i get an answer? please and thank you

Answer 1

`x=-2(y+3)^2-4:`

Vertex: (-4, -3)

Focus: (-33/8, -3)

`x=2(y-3)^2+4:`

Vertex: (4, 3)

Directrix: (x=31/8)

Explanation:

Due to the formula being squared, you know it's going to be a parabola. The 4 at the end is to shift the parabola (-4 = left 4, 4 = right 4). From there you can deduce the vertex and from there the focus and directrix.
