Math Functions

A function that is defined by the set of ordered pairs {(2,1), (4,2), (6,3)} has domain {2, 4, 6}. What is the domain of the function defined by the set of ordered pairs {(0,2), (2,2), (3,-2)} ?

• {2}
• {-2, 2}
• {-2, 0, 3}
• {0, 2, 3}

Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)
• (3,4) (4,-3) (7,4) (3, 8)
• (6,-5) (7, -3) (8, -1) (9, 1)
• (2, -2) (5, 9) (5, -7) (1, 4)

Which graph is NOT a function?

• Graph 1
• Graph 2
• Graph 3
• Graph 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.
