Domain and Range from Graph

Front

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

Back

The domain of a function is the complete set of possible values of the independent variable (usually x) for which the function is defined.

Front

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

Back

The range of a function is the complete set of possible values of the dependent variable (usually y) that results from the function.

Front

What does the notation (-∞, ∞) represent?

Back

It represents all real numbers, indicating that the domain or range includes every possible value.

Front

How do you determine the domain from a graph?

Back

The domain can be determined by identifying all the x-values that the graph covers.

Front

How do you determine the range from a graph?

Back

The range can be determined by identifying all the y-values that the graph covers.

Front

What does the notation [a, b] signify in terms of domain or range?

Back

It signifies that both endpoints a and b are included in the set.

Front

What does the notation (a, b) signify in terms of domain or range?

Back

It signifies that both endpoints a and b are excluded from the set.
