What is the DOMAIN of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

How do you determine the domain from a graph?

Back

To determine the domain from a graph, identify the x-values that the graph covers. This includes all x-values where the graph exists.

Front

What is the RANGE of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you determine the range from a graph?

Back

To determine the range from a graph, identify the y-values that the graph covers. This includes all y-values where the graph exists.

Front

What does the notation -4 ≤ x ≤ 3 mean?

Back

This notation means that x can take any value from -4 to 3, including -4 and 3.

Front

What does the notation -5 ≤ x ≤ 3 represent in terms of domain?

Back

This notation indicates that the domain includes all x-values from -5 to 3, including both endpoints.

Front

What is an example of a discrete domain?

Back

An example of a discrete domain is the set of integers {1, 2, 3, 4}.

Front

What is an example of a continuous domain?

Back

An example of a continuous domain is the interval of real numbers between -1 and 4, represented as (-1, 4).

Front

What is the difference between domain and range?

Back

Domain refers to the input values (x-values) of a function, while range refers to the output values (y-values) of a function.

Front

How can you express the domain of a function using set notation?

Back

The domain can be expressed in set notation, such as D = {x | -4 ≤ x ≤ 3}.
