What are all of the y values or outputs called?

Back

Range

Front

What is the range of the graph if y≥1?

Back

y≥1

Front

Is this mapping a function or not a function? (Example mapping: {(1,2), (2,3), (3,4)})

Back

Function

Front

What is the range? (If given x = 2)

Back

y = 2

Front

What is the range of the set {(4,-4),(3,2),(-1,9),(-6, 4)}?

Back

{-4,2,4,9}

Front

Define 'Domain' in the context of functions.

Back

The set of all possible input values (x-values) for a function.

Front

Define 'Range' in the context of functions.

Back

The set of all possible output values (y-values) for 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, which may or may not be a function.

Front

How can you determine if a mapping is a function?

Back

Use the vertical line test: if a vertical line intersects the graph at more than one point, it is not a function.
