Quiz about Graphing a Function Rule

Question 1

Tell whether the relationship should be represented by a continuous or discrete graph. Explain.
The money raised from a raffle with a $200 prize where the tickets cost $2.50 per person.

Accepted Answer

Discrete; the money raised depends on the number of tickets sold, and since only a whole number of tickets can be sold, this situation is discrete.

Answer

Continuous; the money raised depends on the number of tickets sold, and since any number of tickets can be sold, this situation is continuous.

Answer

Continuous; the money raised depends on the number of tickets sold, and since a person can buy more than one ticket, this situation is continuous.

Answer

Discrete; the $200 prize is a whole number, so the situation is discrete.

Question 2

Tell whether the relationship should be represented by a continuous or discrete graph. Explain.
the height of a tree over time

Accepted Answer

Continuous; a tree grows gradually, not in steps, so this situation is continuous.

Answer

Continuous; a tree grows in steps, so this situation is continuous.

Answer

Discrete; a tree stops growing at a certain age, so this situation is discrete.

Answer

Discrete; a tree never stops growing, so this situation is discrete.

Question 3

Determine whether the function rule models discrete or continuous data.
A movie store sells DVDs for $15 each. The function C(d) = 15d relates the total cost of movies to the number purchased d.

Accepted Answer
