Question

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.

Answer 1

it would be what you started with

Answer 2

okay so 5?

Answer 3

yup

Answer 4

Thank you :)

Answer 5

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

Answer 6

yw

Answer 7

x j(x)
1 8
2 4
3 2

Answer 8

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

Answer 9

what is the question?

Answer 10

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

Answer 11

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

Answer 12

oh ok

Answer 13

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

Answer 14

you got that?

Answer 15

Not really..

Answer 16

two
four
eight
?

Answer 17

doubling each time

Answer 18

oh okay

Answer 19

So 4 would be 0?

Answer 20

no
what is two times eight?

Answer 21

16

Answer 22

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

Answer 23

making the y intercept (the first number ) 16

Answer 24

ohh Okay Thanks :)

Answer 25

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

Answer 26

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