Suppose that a water fountain produces a stream of water that follows the shape of a parabola. assigning the origin of a coordinate system to the point where the water stream emerges from the fountain, a measurement shows that the maximum height of the stream occurs at the point (6, 5). use symmetry to identify a third point and find a quadratic regression equation for the stream of water
a. y= -0.139x^2+1.667x
b. y= 0.135x^2+1.667xc. y= -0.135x^2+1.667xd. y= 0.139x^2+1.667x
