Answer:
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.
Therefore, the quadratic regression equation that fits the data is .
