Write your response in your notebook.
What is the domain and range of the function ?
Explain why the range is limited.

37. Checking for understanding… u1a8 Example 21
What is the domain and range of the function ?
Domain:
Range:
Explain why the range is limited.
The range must be equal to or greater than zero because the absolute value of any non-zero number is always positive.
