Question 756279
Vertex (0,0) and Focus at (0,5)
<br>
Vertex:
(0,0)
(a,b)
<br>
Focus Point:
(0,5)
(0,p)
<br>
we get p = 5
<br>
So because the point of focus located in y-coordinate, so the parabola equation is:
<br>
(x - a)^2 = 4p(y - b)
(x - 0)^2 = 4(5)(y - 0)
x^2 = 20y
<br>
The parabola equation is x^2 = 20y or x^2 - 20y = 0
