Find the values of x in the parallelogram

The center of the circumscribed circle lies on line segment and the longest side of the triangle is equal to the of the circle.

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.

Which of the following graphs could represent a cubic function?
