Dam is rowing a boat away from a dock the graph shows the relationship between the time and sams distance from the dock. evaluate the function for an input of 9

B. After 9 minutes Sam is 80 meters away from the dock.

Step-by-step explanation:

We have been given a graph of function that shows the relationship between the time and Sam's distance from the dock.

Let us see our given options one by one to find the correct choice.

A. After 80 minutes Sam is 9 meters away from the dock.

Upon looking at our graph we can see that y-axis is representing distance in meters and x-axis is representing time in minutes. Range of x is from 0 to 11 So our input cannot be greater than 11.    

Therefore, option A is not a correct choice.

B. After 9 minutes Sam is 80 meters away from the dock.

We can clearly see from our given graph that at 9 minutes distance is 80 meters, which means that after 9 minutes Sam is 80 meters away from the dock. Therefore, option B is the correct choice.

C. After 80 minutes Sam is 80 meters away from the dock.

We can see from our graph that range of x is from 0 to 11 minutes, So our input can not be greater than 11. Therefore, option C is not a correct choice.  

D. After 9 minutes Sam is 3 meters away from the dock.

We can see from our graph that initial value of our function is 20, which means that at time equals 0 minutes Sam was 20 meters away from dock and this distance is increasing with the time. Therefore, option D is not a correct choice.
