Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

where

(h,k) is the vertex

The directrix is

case 1) we have

the vertex is the point (-2,-8)  

The directrix is equal to

case 2) we have

the vertex is the point (3,14)  

The directrix is equal to

case 3) we have

the vertex is the point (-2.5,-7.5)    

The directrix is equal to

case 4) we have

the vertex is the point (3,17)      

The directrix is equal to

case 5) we have

the vertex is the point (4,-7)      

The directrix is equal to

case 6) we have

the vertex is the point (1,6)      

The directrix is equal to

the circle one
