Step-by-step explanation:

5) The graph of an exponential decay function approaches zero, as the values of x grows bigger and bigger.

From the graph, it is only the first graph the has the end behavior of an exponential decay function.

The correct answer is A)  I only  

6) The given function is .

From x=1 to x=3, the grows by a factor of

From x=5 to x=7, the exponential function grows by a factor of

The correct answer is C.

7) The initial value of the car is $20,000.

Since the car loses 20% of its value every year, it has a multiplicative rate of change of

Hence the value will decay exponentially.

The correct answer is B.

8) Let the initial population be , then after 210 minutes,

This implies that:

With initial population is , we want to find the population after 630 minutes.

The correct answer is D

9)

Let the initial population be , then after 60 minutes,

This implies that:

With initial population is , we want to find the population after 240 minutes.

The correct answer is D

10) The initial cost is $40 the unit rate per visit to the Gym is

$2

The total cost y, is given by: , where x is the number of visit.

With $90, you substitute y=90 and solve for x.

The correct answer is A

11) Let , then

Therefore the correct answer is C.  

12) Let , then

This implies that:

The correct answer is C

The ordered pair given in the bottom row can be written  f(9) = 5

Step-by-step explanation:

* I have added screenshot of the complete question as well as

 the diagram

- Function is a relation between x and y, where x has only one

 value of y

- The function notation is f(x) = y , where x is the input and y is

  the output

# Ex: If {(2 , 3) , (10 , -5)} is a function , then it can be written using the

 function notation  f (2) = 3 , f (10) = -5

- We can write any table of function using the function notation

* Lets solve the problem

From the table of the function

∵ x = 2 and f (x) = 6

By using function notation

∴ f (2) = 6

∵ x = 7 and f (x) = 3

By using function notation

∴ f (7) = 3

∵ x = 9 and f(x) = 5

By using function notation

∴ f (9) = 5

∴ The ordered pair given in the bottom row can be written f(9) = 5
