3.  Enter the days and number of rabbits in the table, by pressing the STAT button.

4.  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:

5.  To find the Quadratic Regression equation, follow the same steps but choose option#5 QuadReg, then press Enter twice.
