Answer 1

A discrete function is a function with distinct and separate values. This means that the values of the functions are not connected with each other. For example, a discrete function can equal 1 or 2 but not 1.5.

Let's analize the options:

• Option A: This is continuos, the faucet can fills with 1 gallon, 1.1 gallon, and so. Also any previous value is connected with the next.

,

• Option B: As in option B, the car drives for a continuos time.

,

• Option C: This is a discrete relation, because Jacqueline could not sells a half of a chocolate bar, she sells discrete values of chocolate bars 1, 2, 3, ....

,

• Option D: This is the same as option A.
