Answer 1

A

Explanation:

Answer 2

Scenario, A represents a function.

Explanation:

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.
