Vertex  = (0,0)

Focus = (-6,0)

 

The focus is to the left of the  vertex.....this parabola will open to the left

 

We have  the  form

 

-4px =  y^2

 

p = distance  from focus to vertex  = sqrt [ (-6-0)^2  +  (0 - 0)%2 ] =  sqrt (36)  = 6

 

The equation is

-4 (6)x = y^2

 

-24x  = y^2         which also can be writtten

 

x = (-1/24)y^2
