Domain and Range Notes

Is the relation shown a function?

• No, because the x-value 11 is paired with 5 and 8.

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

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}

• D: {-4, 0, 1, 2}
  R:{-4, -3, 1}

• D: {0, 1, 2, 3, 4}
  R:{1, -3, -4}

• D: {0, 1, 2, -4}
  R: {1, -3, -4, 1}

• Function
• Not a Function

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}

• {105,280,420}

• {3,8,12,105,280,420}

• {38,43,51}

What is the range of the following function, if the domain is {1,7,10}? 
f(x) = x + 4

• {-3,3,6}

• {1,7,10}

• {5,11,14}

• {4,28,40}

What is the Domain of this linear function?

• -3 < x ≤ 5

• x = -1

• 5 < x ≤ -3

• -2 < x ≤ 6
