Rachel has been watching the number of alligators that live in her neighborhood. The number of alligators changes each week. n f(n)
1 48
2 24
3 12
4 6

Which function best shows the relationship between n and f(n)?
f(n) = 48(0.5)n − 1
f(n) = 48(0.5)n
f(n) = 24(0.5)n
f(n) = 96(0.5)n − 1

Step-by-step explanation:

Step-by-step explanation:

the table below shows the amount of chlorine

f(n), in ounces, that was left in the pool after n weeks:

n    1        2      3     5

f(n)  24     12      6    3

We can see that the value of f(n) is decreasing

f(n) does not have common difference. Lets find common ratio

General rule is f(n) = a1 + (r)^(n-1)

Where a1 represents the first term = 24

r represents the common ratio = 0.5

So the function becomes

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
