Answer:
The y-value of the Vertex of the parabola that models the data is 1125.
Step-by-step explanation:
Let the function of parabola is
From the given that it is noticed that the parabolic function passing through the points (1,1045), (3,1105) and (5,1125). It means the function must be satisfied by these points.
....(1)
....(2)
....(3)
On solving (1), (2) and (3) we get,
Therefore the equation of parabola is
The vertex of the parabola is
Therefore the vertex is (5,1125) and y-value of the Vertex of the parabola that models the data is 1125.
