Graph 1.

Front

Look at the graph. Is the relation a function?

Back

No.

Front

What is a function?

Back

A relation where each input (x-value) has exactly one output (y-value).

Front

What is the vertical line test?

Back

A method to determine if a graph represents a function; if a vertical line intersects the graph at more than one point, it is not a function.

Front

Can a function have the same y-value for different x-values?

Back

Yes, a function can have the same y-value for different x-values.

Front

What is an example of a function?

Back

f(x) = x^2 is a function because each x-value has one corresponding y-value.

Front

What is an example of a non-function?

Back

The relation {(1,2), (1,3)} is not a function because the x-value 1 has two different y-values.
