Question 754005
Vertex (4,-6) and Focus at (6,-6)


Because the y-vertex and y-focus is same, the equation of parabola is:
(y - b)^2 = 4p(x - a)


Vertex:
(4,-6)
(a,b)


Focus Point:
(6,-6)
((p+a),b)



If
b = -6
a = 4



then,
p + a
6 = p + 4
2 = p



the parabola equation is:
(y - b)^2 = 4p(x - a)
(y - (-6))^2 = 4(2)(x - 4)
(y + 6)^2 = 8(x - 4)
