Functions and Relations, Domain, Range

Front

What are all of the x values of a relation called?

Back

Domain

Front

What is a function?

Back

A relation where each x-value has only one y-value paired with it.

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

Identify the relation that is not a function: {(0,1), (1,2), (2,3), (3,4)}, {(0,2), (1,3), (4,3), (1,2)}, {(1,3), (4,2), (2,0), (3,4)}, {(1,2), (2,2), (3,2), (4,2)}

Back

{(0,2), (1,3), (4,3), (1,2)}

Front

What is the range of a function?

Back

The set of all possible y-values that a function can output.

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

What does it mean if a relation has two y-values for one x-value?

Back

It is not a function.

Front

What is a relation in mathematics?

Back

A set of ordered pairs, where each pair consists of an x-value and a y-value.

Front

How can you determine if a graph represents a function?

Back

By using the vertical line test.

Front

What is the domain of a function?

Back

The set of all possible x-values that a function can accept.
