Answer:
Scenario, A represents a function.
Explanation:
The question is the missing the graph
See the attached figure.
A function is a relationship where each input has a single output.
So, according this definition we will test scenarios A and B
Scenario A :
As shown at scenario A, each value of the time (input) has a single value from the distance (output)
So, scenario, A represents a function.
Scenario B :
As shown at scenario B, there is a value of the height (input) has two values from the time (output)
the number 70 in. from the height has two values which are 54.6 and 53.11 sec
So, scenario, B dose not represent a function.
