A function of x containing four ordered pairs is shown below.

{(2,3) , (4,5) , (6,7) , (8,9)}

What is the range of the function?

• {3,5,7,8}

• {2,4,7,9}

• {2,4,6,8}

• {3,5,7,9}

{(-3, 5) , (8, -6) , (2, 5) , (-6, 1) , ? }

Which ordered pair can replace the missing value and make this set NOT a function?

• (5,2)

• (-6, 7)

• (-2, 0)

• (3, -6)
