Week 4 - Domain and Range Review

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 determine the domain of a function from its graph?

Back

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

Front

How do you determine the range of a function from its graph?

Back

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

Front

What does the notation 0 < x < ∞ represent?

Back

This notation indicates that x can take any value greater than 0, extending to positive infinity.

Front

What does the notation 1 ≤ x ≤ 7 represent?

Back

This notation indicates that x can take any value from 1 to 7, including both endpoints.

Front

What does the inequality x > 2 mean?

Back

This inequality means that x can take any value greater than 2.

Front

What does the inequality x ≤ -3 mean?

Back

This inequality means that x can take any value less than or equal to -3.

Front

What is the significance of closed intervals in domain and range?

Back

Closed intervals include the endpoints, meaning the values at the endpoints are part of the set.

Front

What is the significance of open intervals in domain and range?

Back

Open intervals do not include the endpoints, meaning the values at the endpoints are not part of the set.
