Relations and Functions

Front

What are all of the y values or outputs called?

Back

Range

Front

Is this graph a function or not a function? (Example: A vertical line intersects the graph at more than one point)

Back

Not a Function

Front

What are all of the x values or inputs called?

Back

Domain

Front

Is this graph a function or not a function? (Example: A graph passes the vertical line test)

Back

Function

Front

Is this mapping a function or not a function? (Example: Each input has exactly one output)

Back

Not a Function

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What is a relation?

Back

A set of ordered pairs (x, y).

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

What is the difference between domain and range?

Back

Domain is the set of all possible input values (x), while range is the set of all possible output values (y).

Front

Can a function have the same output for different inputs?

Back

Yes, a function can have the same output for different inputs, as long as each input has only one output.
