Unit 3 Review

Question 1

John saves for a maximum of 12 months. The graph shows John's savings as a linear function of x, the number of months he saves.

Describe the domain and range of the function for this situation.

• The domain for this function is all real numbers greater than or equal to 0 and less than or equal to 12

• The domain for this function is all real numbers greater than or equal to 300 and less than or equal to 1500

• The range is all real numbers greater than or equal to 0 and less than or equal to 12.

• The range is all real numbers greater than or equal to 300 and less than or equal to 1500.

• The domain of the function is all real numbers greater than 0.
