Relations and Functions

Front

What is a set of ordered pairs called?

Back

A relation.

Front

Does the graph represent a function? (Example: A vertical line test shows it intersects the graph at more than one point)

Back

No.

Front

Is this table a function or not a function? (Example: Input: 1, Output: 3; Input: 2, Output: 6; Input: 3, Output: 9; Input: 4, Output: 12)

Back

Function.

Front

List the ordered pairs from the following set: (1,3), (2,6), (3,9), (4,12)

Back

(1,3), (2,6), (3,9), (4,12).

Front

Does the graph represent a function? (Example: A graph that fails the vertical line test)

Back

No.

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 is a function?

Back

A relation where each input has exactly one output.

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 more than once, it is not a function.

Front

What are independent and dependent variables in a function?

Back

Independent variable is the input (x), and dependent variable is the output (y).
