Putting It All Together

Answer these open ended questions on your own or with others to form deeper math connections.

Open-ended question 1

In a graph of a piecewise function, some endpoints may be open and others closed. How is this reflected in the notation for the domain and range of a function?

Text and math input

Open-ended question 2

What key features of a piecewise function graph would you use to state the domain of the function? The range?

Text and math input

Open-ended question 3

How is the range of a piecewise function sometimes expressed differently than the domain? Why is this the case?
