Find the vertex,axis of symmetry, x intercepts, y intercept
Focus (1/2, negative2) directrix y= negative5/2
y= negative 2
y= negative 5/2 so midpoint formula to get k= negative 9/4
focus 1/2 give me h
so vertex = (1/2,-9/4 axis of symmetry x= 1/2
problem I have is figuring out what p=
if I had 2 and 3 as the yintercepts then I would know p= 1/2 then do 1/4p =1/2 then I know what to do.
