Explain how range and domain are related to the concept of function mapping.

• The range and domain determine the number of solutions of a function.

• The range and domain determine the slope of a function.

• The range and domain are used to calculate the derivative of a function.

• The range and domain define the set of possible inputs and outputs of a function.

What is the range of a function?

• The range of a function is the set of all possible output values (y-values) that the function can produce.

• The range of a function is the slope of the function.

• The range of a function is the set of all possible input values (x-values) that the function can take.

• The range of a function is the same as the domain of the function.
