Functions and Vertical Line Test

For the function

{(0,1), (1,-3), (2,-4), (-4,1)},

what is the domain?

• {1, -3, -4,}

• {0, 1, 2, -4}

• {0, 1, 2, 3, 4}

• {0,1,2}

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

Does this mapping diagram represent a function?

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

A relation that pairs each input with exactly one output is called a...

• Relation

• Linear

• Exponential

• Function

Which graph does NOT pass the vertical line test?

• Graph 1
• Graph 2
• Graph 3
• Graph 4

Another name for the "y-values" or "outputs" is ...

• Domain

• Range

• Relation

• 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.

All of the "x value" or "inputs" are called what?

• Domain

• Range

• Relation

• Function

Is this a function? Explain.

• Yes; it passes the horizontal line test.
• No; it is not a straight line.
• Yes; it passes the vertical line test.
• No; there is a line connecting the dots.

Is this a function?

• Yes, it is a function

• No, it is not a Function
