Cubic functions 2




Exercise 2: cubic functions questions 2 and 3 are due for monday. Exercise 3 question 3 is also due.




Reminder to everyone...test on tuesday...good luck. Were aloud a 8x11 formula sheet... front and back if you want. We can use this for all tests.


We also did a bunch of random questions on rabbits breeding. so heres some pictures of how we figured out the problems.
The 3 questions mr max made for us were..
1)create an equation using regression to model the rabbit population over time.
2)How many rabbits would you expect using this model after one year?
3)If the rabbit population in the future is known to be 500 animals, how much time elapsed?
We used expreg for this problem.
you enter the table into the calculator. Then go (zoom) (9) after (on) your (2nd) (y=) stat plot. there are also ways like y=2.16*2.37^12 (the 12 is months.)
Have a good weekend.
