2. mariomintchev

chris, do you know how to do this?

3. becca18

That's too much work.

4. mariomintchev

not really.

5. mariomintchev

rules are like f(x)=e^x or p(t)=p/e^kt

6. becca18

Ohhh I'll try

7. fr33

LOL, no its not, just evaluate time with respect to Cells. like f(x) = x C(t) = t Thats a Table of values, just evaluate each cells with respect time.

8. mariomintchev

i mean i know that they double. i just need the exact function.

9. becca18

I tried.. It didn't come out right.

10. mariomintchev

FR33 help!

11. fr33

Whats the function? I cant resolve it without it...

12. mariomintchev

i need the function. that is what my hw is asking me for.

13. mariomintchev

here's part A: (a) A genetic engineer is growing cells in a fermenter. The cells multiply by splitting in half every 15 minutes. The new cells have the same DNA as the original ones. Complete the following table.

14. mariomintchev

i filled in 1600 and 3200

15. mariomintchev

and part B is asking me for the function

16. mariomintchev

or the rule of the function

17. fr33

Wow this seems complicated...

18. mariomintchev

not really. i just cant figure it out cause i suck at math.

19. mariomintchev

its like what you do to get the next thing... like add 2 or multiply by 5 but its a little more complex than that.

20. fr33

What is the main concept ofthe lecture? Like what Chapter and section of the book..?

21. mariomintchev

Exponential and Logarithmic Functions
