Find the function rule.

• y = 6x + 1

• y = -2x -8

• y = -2x + 8

• y = 2x -8

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.

You buy x pounds of cherries for $2.99/lb. What is a function rule for the amount of change C you receive from a $50 bill?

• C = 2.99x - 50

• C = 50x - 2.99

• C = 50 - 2.99x

• C = 2.99 - 50x
