Front

Is this table a function or not a function?

Back

Not a Function

Front

Which relation is NOT a function? {(1,-5), (-1,6), (1,5), (6,-3)} or {(2,7), (3,7), (4,7), (5,8)}?

Back

{(1,-5), (-1,6), (1,5), (6,-3)}

Front

All of the y values or outputs are called what?

Back

Range

Front

For the function {(0, 1), (1, -3), (2, -4), (-4, 1)}, write the domain and range. (x,y)

Back

D:{0, 1, 2, -4} R:{1, -3, -4}

Front

What is the domain? {-2, -1, 0, 1, 8} or {-2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}?

Back

{-2, -1, 0, 1, 8}

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What is the domain of a function?

Back

The set of all possible input values (x-values).

Front

What is the range of a function?

Back

The set of all possible output values (y-values).

Front

How can you determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph at more than one point, it is not a function.

Front

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

Back

Each output is paired with exactly one input.
