The point lies on the parabola

The point lies on the parabola and is the point.
solution:
-> parabola is , the point in vertex (minimum)
-> parabola is , the point in vertex (maximum)

writ both equations in vertex form:





=> vertex is at (,)=>the point





=> vertex is at (,)=>the point
since both points have same coordinate, the point lies vertically below the point because coordinate of the point is greater than coordinate of the point


a) Show this information on a neat diagram



b) Find the least value of the length of line AB
the length of line
