Front

Does this relation represent a function? (1,5), (1,6), (1,7), (1,8), (1,9)

Back

No

Front

Is this graph a function or not a function?

Back

Function

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What is the Vertical Line Test?

Back

A method to determine if a graph represents a function by checking if a vertical line intersects the graph at more than one point.

Front

Can a function have the same output for different inputs?

Back

Yes, a function can have the same output for different inputs.

Front

What is an example of a function?

Back

f(x) = x + 2 is a function because each input x has one output.

Front

What is a non-function?

Back

A relation where at least one input has multiple outputs.
