Which ordered pair below would prevent this table from being a function?

• (10, 10)
• (2, 4)
• (6, 1)
• (-2, 0)

Does this mapping diagram represent a function?

• No, because there are repeating input values
• Yes, because there are no repeating input values

Which graph does NOT pass the vertical line test?

• 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.

Evaluate f(-2) if f(x) = x²+ 3

• -1
• 1
• 7
• -7

If h(a) = 3 - 2a

Find h(-3).

• 12
• -2
• -3

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}

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values
• No, because the vertical line test shows there are repeating input values
