Front

What are all of the y values or outputs in a function called?

Front

What is the term for a mapping that does not assign exactly one output for each input?

Back

Not a Function

Front

What is the range of the graph defined by -2 ≤ y ≤ 10?

Back

Front

What is the domain of the graph defined by -3 ≤ x ≤ 3?

Back

-3 ≤ x ≤ 3

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

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

How can you determine if a graph represents 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.

Front

What does it mean if a function is defined as 'not a function'?

Back

It means that at least one input is associated with multiple outputs.
