## anonymous one year ago What would the Y- INtercept be? Al is monitoring the decay of a population of fungi. It is reducing in half every four weeks. The population started at 5.

1. anonymous

it would be what you started with

2. anonymous

okay so 5?

3. anonymous

yup

4. anonymous

Thank you :)

5. anonymous

y intercept is what you get when ](t=0\) or $$x=0$$ or whatever your variable is

6. anonymous

yw

7. anonymous

x j(x) 1 8 2 4 3 2

8. anonymous

what about in this graph? would it be j(x)

9. anonymous

what is the question?

10. anonymous

are you supposed to find an explicit formula for j(x) or are you supposed to find the y intercept as well?

11. anonymous

I just need to know the y intercept because the question is to list the y intercept from least to greatest and I know what the other 2 are im just lost with those 2

12. anonymous

oh ok

13. anonymous

look at the pattern backwards to figure out what you would get if x = 0 2 , 4 , 8 , ?

14. anonymous

you got that?

15. anonymous

Not really..

16. anonymous

two four eight ?

17. anonymous

doubling each time

18. anonymous

oh okay

19. anonymous

So 4 would be 0?

20. anonymous

no what is two times eight?

21. anonymous

16

22. anonymous

yeah so the pattern will be $16,8,4,2,1,\frac{1}{2},...$

23. anonymous

making the y intercept (the first number ) 16

24. anonymous

ohh Okay Thanks :)

25. anonymous

yw guess you got some more y intercepts to find right?

26. anonymous

I found the other 2, It was just the graph and an equation.
