Which of the following points lie on the parabola x² = 4ay?

Given that the equation of the parabola is x² = 4ay.

We know the parametric equation of the point on the parabola is (2at, at²)

∴The correct option is B

The length of the latus - rectum of the parabola 4y² + 2x – 20y + 17 = 0 is

The length of the latus - rectum of the parabola x² – 4x – 8y + 12 = 0 is

The focus of the parabola y = 2x² + x is

The equation of the parabola whose focus is (1, - 1) and the directrix is x + y + 7 = 0 is
