Question

The situation that is best modeled by a discrete graph is
the daily records of the distance of each hotel from home during a cross-country trip.
the height of a wave over time.
the speed of a motorcycle over the distance it travels.
the body temperature of an athlete during a workout.

Answer 1

for data to be discrete, it must consist of separate data points rather than a continuous range

if you look at the first answer choice, "the daily records of the distance of each hotel from home during a cross-country trip." this would consist of separate data points

ex:
point 1: distance between hotel 1 and home,
point 2: distance between hotel 2 and home, etc. as discrete points.

the rest of the answer choices would consist of continuous data over a range
