Answer:
[tex]y=-x^2+3x+11[/tex]
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
[tex]y=ax^2+bx+c[/tex] .... (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.
[tex]y=(-1)x^2+(3)x+(11)[/tex]
[tex]y=-x^2+3x+11[/tex]
Therefore, the quadratic regression equation that fits the data is [tex]y=-x^2+3x+11[/tex].
