Graphing a Function Rule

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.

• Continuous; the money raised depends on the number of tickets sold, and since any number of tickets can be sold, this situation is continuous.
• 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.
  
• 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.
• Discrete; the $200 prize is a whole number, so the situation is discrete.

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

• Continuous; a tree grows gradually, not in steps, so this situation is continuous.
• Continuous; a tree grows in steps, so this situation is continuous.
• Discrete; a tree stops growing at a certain age, so this situation is discrete.
• Discrete; a tree never stops growing, so this situation is discrete.

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.

• discrete
• continuous

Determine whether the function rule models discrete or continuous data.
A produce stand sells roasted peanuts for $2.99 per pound. The function C(p) = 2.99p relates the total cost of the peanuts to the number of pounds purchased p.
