The Golden Gate, located in San Francisco, California , is the tallest bridge in the world, with its tower extending 746 feet above the water and the floor of the bridge extending 220 feet above water.
Notice that the supporting cables of the Golden Gate Bridge approximate the shape of a parabola.

This parabola can be modeled by the quadratic function y = 0.00012x2 + 6, where x represents the distance form the axis of symmetry and y represents the height of the cables. The related quadratic equation is 0.00012x2 +6 = 0.

Calculate the value of the discriminant
