Answer:
Those that can be graphed using continuous graph are,
total cost, c, of buying g pounds of broccoli
speed of a car, s, as it accelerates over time
total distance, d, that has been driven over time, t
decrease in outside temperature, f, one evening over time, t
Explanation:
we look at these one by one,
total cost, c, of buying b cans of beans
since the cans are discrete, the graph is also discrete (not continuous)
total cost, c, of buying g pounds of broccoli
Here, the g pounds can have any value, we assume that the cost has a linear relationship to the pounds of broccoli i.e. if you buy double the broccoli you double the cost. hence this can be represented as a continuous graph.
speed of a car, s, as it accelerates over time
This is a continuous graph since speed and time are continuous
number of stamps, s, needed to mail p postcards
This is discrete since the stamps wil be discrete
total distance, d, that has been driven over time, t
This is also continuous
decrease in outside temperature, f, one evening over time, t
Temperature is also continuous over time
