Domain and Range of Situations

Why do we need to be able to determine if a function is continuous or discrete before we write the domain and range?

• It tells us if we need to write the domain/range as a list or in inequality notation.

• To determine the function's slope and intercepts.
• It helps determine the order of the domain/range.

• We need it to simplify the function's equation.

What is the range of the situation?

Do not type spaces, and don't forget the { }.

Is the function continuous or discrete for this situation?

• Continuous

• Discrete
