Answer:
![y=-x^2+3x+11](https://tex.z-dn.net/?f=y%3D-x%5E2%2B3x%2B11)
Step-by-step explanation:
The given data table is
Number of seconds : 0 1 2
Height (in feet) : 11 13 13
We need to find quadratic regression equation that fits these data.
The general form of quadratic regression equation is
.... (1)
Using the graphing calculator we get
a = -1 , b = 3 and c=11
Substitute these values in equation (1), to find the quadratic regression equation that fits these data.
![y=(-1)x^2+(3)x+(11)](https://tex.z-dn.net/?f=y%3D%28-1%29x%5E2%2B%283%29x%2B%2811%29)
![y=-x^2+3x+11](https://tex.z-dn.net/?f=y%3D-x%5E2%2B3x%2B11)
Therefore, the quadratic regression equation that fits the data is
.
