Q&A Given M and N are fixed points on y axis with coordinates (0,1), (0,-1). Point P is a dynamic point on parabola y = \dfrac{1}{4}x^2

Multiple choice A parabola with a vertical axis has its vertex at the origin and passes through point (7,7). The parabola intersects line y = 6 at two points. The length of the segment joining these points is

Multiple choice The coordinates of the vertex of the parabola whose equation is y = 2x^2 + 4x - 5 are
