None of the above is true
Equation of a Parabola When The Vertex IS (h k ) and Parabolic Curve -
Equation of a Parabola When The Vertex IS (h k ) and Parabolic Curve
The equation of the parabola when the axis is parallel to x-axis
can be written as
The vertex of the parabola is O(0, 0). Now the origin is shifted to O’(h, k) without changing the direction of axes, its equation becomes
Thus its focus is S (a + h, k), latus rectum = 4a and the equation of the directrix is
x = h – a, i.e. x + a – h = 0
-
The given equation is
Hence none of the above is true
