
Enter the days and number of rabbits in the
table, by pressing the STAT button.

To find the linear regression model after you have
entered the numbers, press the STAT button and
choose CALC option with the left right arrow. Then
choose option #4, LinReg (ax+b) and then press Enter
twice. Here is what should be on the screen:

To find the Quadratic Regression equation,
follow the same steps but choose option#5
QuadReg, then press Enter twice.

After entering the following chart in excel:

From the menu select Insert then click Chart and
choose X Y (Scatter). To get the equations, select one
of the points and right click add trendline. Then
select Linear and do the same for Exponential. Click
on the box that says show equation on chart.
