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.
The money raised from a raffle with a $200 prize where the tickets cost $2.50 per person.
a)
Continuous; the money raised depends on the number of tickets sold, and since any number of tickets can be sold, this situation is continuous.
b)
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.
c)
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.
d)
Discrete; the $200 prize is a whole number, so the situation is discrete.
2.
Tell whether the relationship should be represented by a continuous or discrete graph. Explain.
the height of a tree over time
the height of a tree over time
a)
Continuous; a tree grows gradually, not in steps, so this situation is continuous.
b)
Continuous; a tree grows in steps, so this situation is continuous.
c)
Discrete; a tree stops growing at a certain age, so this situation is discrete.
d)
Discrete; a tree never stops growing, so this situation is discrete.
3.
Determine whether the function rule models discrete or continuous data.
