The equation of the quadratic relationship is y=−0.07(x−10.76)²+14.8. that equation references the coordinates (10.76,14.8). what is the significance of those coordinates?

A quadratic relationship that is given in the form , where , and  are constants, tells a lot about the quadratic graph

means the graph is ∪ shape
means the graph is ∩ shape

The minimum/maximum point of the graph is given by 

We are given a quadratic equation
, where:





So, the graph is ∩ shape because  and the coordinate for maximum point is (10.76, 14.8)

The significance of (10.76, 14.8) is that the coordinate shows the maximum point of the quadratic graph
