What is the quadratic regression equation that fits these data?

number of seconds height (in feet)

0

11

1

13

2

13

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 .
