Flashcard - Finding Domain and Range in Interval Notation

Front

What is interval notation?

Back

Interval notation is a mathematical notation used to represent a range of values on the number line, using parentheses and brackets to indicate whether endpoints are included or excluded.

Front

What does the bracket [ ] indicate in interval notation?

Back

The bracket [ ] indicates that the endpoint is included in the interval.

Front

What does the parenthesis ( ) indicate in interval notation?

Back

The parenthesis ( ) indicates that the endpoint is not included in the interval.

Front

Express the following in interval notation: -8 ≤ x < 8

Back

[-8, 8)

Front

Express the following in interval notation: x > -5

Back

(-5, ∞)

Front

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

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 find the domain from a graph?

Back

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

Front

How do you find the range from a graph?

Back

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