Vertex  ( -2, 5 )    focus  (-2, 6)

 

The parabola opens upward since the focus is above the vertex

 

p  =  the distance from the vertex to the focus  =  1

 

So  we have

 

4p(y - 5) = (x - ( -2))^2

 

4(1)(y - 5)  =  ( x + 2)^2

 

4 ( y - 5)  = ( x + 2) ^2        divide both sides by 4

 

y - 5 =  (1/4)(x + 2)^2       add 5 to both sides

 

y  = (1/4) (x + 2)^2   + 5
