Domain and Range of Continuous Data with Endpoints

Domain and Range of Continuous Data with Endpoints

Continuous Functions

Yesterday we learned how to find the domain and range of continuous data (graphs with connected points).

Multiple Choice

What is the definition for Domain?

• The set of all X values

• The set of all Y values

Multiple Choice

What is the definition for Range?

• The set of all X values

• The set of all Y values

Remember, we capitalize the N in domain to help us remember that we focus on the sides of our rectangle and we capitalize the E in range to help remember that we focus on the bottom and top of our rectangle.

Multiple Choice

How do we read Domain of Continuous Data?

• Left to Right

• Bottom to Top

Multiple Choice

How do we read Range of Continuous Data?

• Left to Right

• Bottom to Top

We learned that we use inequality symbols when writing domain and range for continuous data.

Multiple Choice

When we have a closed circle, what inequality symbol do we use? (Check the correct answer)

• Less than

• Less than or Equal to

Multiple Choice

What is the range for the graph shown in the slide before?

•  $-6\le x\le5$
