Domain and Range

Front

What is the range?

Back

The set of all y-values.

Front

In the relation {(-1, 2), (-2, 4), (2, 5), (0, -2), (2, 0)}, what domain value corresponds to the range value -2?

Back

0.

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

Is the relation {(1,2), (1,3), (2,4)} a function? Why?

Back

No, because the x-value 1 has two y-values paired with it.

Front

What is the DOMAIN?

Back

The set of all x-values.

Front

What is the definition of a function?

Back

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

Front

Identify the domain of the function {(3,5), (4,6), (5,7)}.

Back

D: {3, 4, 5}.

Front

Identify the range of the function {(3,5), (4,6), (5,7)}.

Back

R: {5, 6, 7}.

Front

What does it mean if a relation is not a function?

Back

It means at least one x-value is paired with more than one y-value.

Front

Given the function {(1,2), (2,3), (3,4)}, what is the range?

Back

R: {2, 3, 4}.
