Domain & Range

Front

What are all of the x values or inputs in a function called?

Back

Domain

Front

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

Back

Range

Front

Is this graph discrete or continuous?

Back

Continuous

Front

Does the graph represent a function? If you have an x value that has 2 'y' values, is it a function?

Back

No, because the vertical line test shows there are repeating input values.

Front

What is the range of the graph? Remember: Range is y!

Back

1 ≤ y ≤ 5

Front

What is the definition of 'Domain' in a function?

Back

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

Front

What is the definition of 'Range' in a function?

Back

The set of all possible output values (y values) for a function.

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

If a function has a domain of {1, 2, 3}, what are the possible x values?

Back

1, 2, 3

Front

If a function has a range of {4, 5, 6}, what are the possible y values?

Back

4, 5, 6
