Given:
Vertex = ( h,k ) = ( -2,1 )
Focus = ( -2,4 )
To find:
We have to find the equation of parabola for given vertex and focus
Solution:
When vertex (h,k) is known
for vertical parabola
Here x = -2 is the vertical line on which focus and vertex lies
So the parabola is vertical
a = 4-1 = 3
So equation is
The equation of required parabola is
