Front

A set of ordered pairs is called a ________?

Back

Relation

Front

Is this graph a function or not a function?

Back

Not a Function

Front

All of the y values or outputs are called the ________?

Back

Range

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

Front

What is the definition of a function?

Back

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

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 the Vertical Line Test determine?

Back

Whether a graph represents a function; if a vertical line crosses the graph more than once, it is not a function.

Front

If a function has the ordered pairs (2,3), (3,4), (2,5), is it a function?

Back

No, because the x-value 2 has two different y-values (3 and 5).
