If you see TWO x-values that are the same, the relation is NOT a function.

• True

• False

To find out if a relation is a function, you can ask yourself this question...

• Is there more than one x-value that is the same?

• Is there more than one y-value that is the same?

• Is there more than one ordered pair that is the same?

• Can I graph this?

What is the Vertical Line Test?

• a method in which you draw a vertical line to determine whether a given relation on a graph is a function or not

• drawing a vertical line on the graph to determine if the line is nonlinear or not

• drawing a curved line on the graph

• drawing a horizontal line on the graph to determine whether a given relation on a graph is a funcation or not.

The graph of a function must pass the

• Vertical Line Test

• Nonlinear test

• Mathematics Test

• mapping test

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.
