You create a graph to represent the number of people who join the Equestrian Club during a 7 day period. Would this be a continuous or discrete graph?

• The graph will be continuous because there can be any number of people signing up each day.

• The graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.

• The graph will be discrete because some day the number of available people to sign up for the club will run out.
