function and relation

Front

Is the relation a function? Why?

Back

No, because the x-value 11 has two y-values pair with it.

Front

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

Back

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

Front

A relation where every input matches with exactly one output is called what?

Back

Function

Front

If a vertical line intersects a graph at more than one point, the graph represents a function. True or False?

Back

False

Front

What is the definition of function?

Back

Every input has only ONE output.

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

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

Back

Each output is paired with exactly one input.

Front

What is a 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.
