Function or Not?

Front

Does the graph represent a function?

Back

No, because the vertical line test shows there are repeating input values.

Front

Which set of values is a function?

Back

(6,-5) (7, -3) (8, -1) (9, 1) because every input has only one output.

Front

Which graph does NOT pass the vertical line test?

Back

Graph 1 does not pass the vertical line test.

Front

What is the definition of a function?

Back

A function is a relation where every input has only ONE output.

Front

Is this set of ordered pairs a function? (3,4) (4,-3) (7,4) (3, 8)

Back

No, it isn't a function because an x value repeats but has different y values.

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 output for different inputs?

Back

Yes, a function can have the same output for different inputs, as long as each input has only one output.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represent a point on a graph.

Front

What does it mean for a function to be one-to-one?

Back

A one-to-one function means that each output is paired with exactly one input, and no two different inputs have the same output.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for the function.
