Discrete or Continuous?

• Discrete

• Continuous

• {-2, 3, 7}
• [-2, 3]
• {1, 2, 2, 3, 4}
• [1, 4]

Is the relation a function? Why?

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.

To celebrate the holiday season this year, Six Flags has created an extreme six-lane, tubing hill with real snow called the “Superman’s Awesome SNOW Tubing Ride.”  The cost of each ticket for one day is $35.  The number of tickets purchased by groups is given by the domain {3, 8, 12}.  Which would be a reasonable range for the total cost of the tickets the groups would pay? 

• {3,8,12}
