Question

equation of parabola ​

Answer 1

The standard form is (x - h)2 = 4p (y - k), where the focus is (h, k + p) and the directrix is y = k - p. If the parabola is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the x-axis, it has an equation of (y - k)2 = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - p.

Answer 2

Equation of parabola

• y^2=4ax
• y^2=-4ax

• x^2=4ay
• x^2=-4ay
