What is the domain and range of the function in terms of the problem situation?Use complete sentences in your answer.Sample Answer: The domain is all real numbers from 0 to 20, and the range is all realnumbers from 0 to –16.© 2008 Carnegie Learning, Inc.6. Determine the x-intercepts of the graph. Interpret the meaning of the x-intercepts in theproblem situation. Use complete sentences in your answer.Sample Answer: The x-intercepts are 0 and 20. The intercepts indicate the points wherethe diver enters and exits the water. The intercept (20, 0) gives the horizontal distance thediver travels.238 Chapter 3 ■ Assessments Georgia Mathematics 1
