Question

Help don’t understand it

Answer 1

Answer:

D.

Step-by-step explanation:

The domain is the interval of x numbers. In this case the x values go from 0 to 10.

We know 10 is the maximum because they have said so as there are only 10 tickets available at a time. Also the graph agrees with that.

So the answers cannot be A or C since there is a limit to the domain.

B cannot be the answer since there cannot be fractional tickets (1 1/2, 5 1/8 etc.). The tickets are countable and they should be whole numbers. Real numbers include fractions, decimals too.

Therefore, the answer is D.

Hope this helps! :)
