Question

For each situation decide if the DOMAIN is discrete or continuous. Explain your thinking.

A. The air temperature over the course of a day

B. The cost of hot dogs at
concession stand

C. The distance traveled on a road
trip

D. The cost of parking for a certain number of hours at a parking garage

Answer 1

A and C are discrete, B and D are continuous

Explanation:

A is continuous because the temperature of the air can be any possible temperature and every possible number in between.

B is discrete because the cost can only be an exact amount of money. It couldn't be 88.7 centers, for example.

C is continuous because the distance includes every possible measurement between 0 and the total number of miles.

D is the same as B.
