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 = negative 0.139 x squared + 1.667 x
c.
y = negative 0.135 x squared + 1.667 x
b.
y = 0.135 x squared + 1.667 x
d.
y = 0.139 x squared + 1.667 x
