Domain and Range from Graphs

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

How do you find the Domain from a graph?

Back

Identify the x-values for which the function is defined.

Front

How do you find the Range from a graph?

Back

Identify the y-values that the function can output.

Front

What does it mean if a function has a Range of y ≥ -4?

Back

The function outputs all values greater than or equal to -4.

Front

What does it mean if a function has a Range of y ≤ 6?

Back

The function outputs all values less than or equal to 6.

Front

What is the Domain of the set {-5, -2, 1, 4}?

Back

The Domain consists of the x-values: -5, -2, 1, and 4.

Front

If all y values are outputs, what are they called?

Back

Range.

Front

What is the Range if the function outputs y > 0?

Back

The Range consists of all positive y-values.

Front

What is the significance of the Range in a function?

Back

It indicates the possible outputs of the function based on its Domain.
