Understanding Domain and Range

The video tutorial explains how to identify the domain and range of a function f(x) using a table. It defines the domain as the set of all possible inputs (X values) and the range as the set of all possible outputs (Y values). The tutorial guides viewers on how to list these values in order, using curly brackets, and provides an example with specific values. The video concludes with a summary of the domain and range for the given function.

What is the domain of a function?

• The set of all possible outputs

• The set of all possible inputs

• The set of all possible values

• The set of all possible functions

What does the range of a function represent?

• The set of all possible inputs

• The set of all possible outputs

• The set of all possible variables

• The set of all possible constants

How should the domain values be listed?

• In random order

• From greatest to least

• From least to greatest

• In alphabetical order

If a value in the range occurs more than once, how should it be listed?

• Do not list it at all

• List it multiple times

• List it twice

• List it only once

Which of the following is a correct domain for the function f of X?

• {-3, 0, 3, 6, 11}

• {-3, -2, -1, 0, 1, 2, 3}

• {11, 6, 3, 2}

• {3, 2, 1, 0, -1, -2, -3}

Which of the following is a correct range for the function f of X?

• {-3, -2, -1, 0, 1, 2, 3}

• {3, 2, 1, 0, -1, -2, -3}

• {2, 3, 6, 11}

• {11, 6, 3, 2, 3}
