Question

Find the vertex, focus, directrix, and focal width of the parabola.

x = 4y^2

Answer 1

I put
Vertex: (0, 0); Focus: ((1/16),0) ; Directrix: x = 1/16 ; Focal width: 16

Which was wrong.

Answer 2

Those answers don't help, show your work/attempts.

Answer 3

looks like your focus is on the ruddy directrix itself. :>

Answer 4

\[\large 4p y = x^2\]looks like you got p=1/16

The directrix and focus intersect, which should tell you that there's a problem.
