Summary Statement

Question 1

Final Project Submission. This week, you will build upon what you have already submitted by refining and adding to it. For the final submission, you will revisit slide 5 and add slides 6 and 7 to conclude your Final Project submission.

• Based on feedback that you received from your Final Project Milestone submission, revise the slides/web pages you have submitted. Then, follow the instructions here for the remaining slides/web pages.
• Slide/web page 5: In Week 3, you identified five important people who helped in the development or growth of your chosen medium during its evolution. This week, analyze the contributions of these people to the history of the medium and add that information to the slide.
• Slide/web page 6: Make a summary statement about the effect of mass communication on people today based on the information collected for slides/web pages 1–5. Add a short bulleted list that highlights three predictions about where mass communication could lead people in the future.
• Slide/web page 7: Provide a total of 8 sources for your project. For all sources, record where you found information about them. Include all relevant information about the source (author; date of publication; the book, article, or website; etc.).

Question 2

Do not use your calculator for Parts 1 through 4.

Let f be the function defined as follows:

if

x equals the piecewise function three minus x for x is less than one, a x squared plus b x for one is less than or equal to x is less than two, and five x minus ten for x is greater than or equal to two where a and b are constants.

1. If a = 2 and b = 3, is f continuous at x = 1? Justify your answer.

1. If a = 2 and b = 3, is f continuous at x = 1? Justify your answer.
   
2. Find a relationship between a and b for which f is continuous at x = 1.
   Hint: A relationship between a and b just means an equation in a and b.
   
3. Find a relationship between a and b so that f is continuous at x = 2.
   
4. Use your equations from parts (ii) and (iii) to find the values of a and b so that f is continuous at both x = 1 and also at x = 2?
   
5. Graph the piece function using the values of a and b that you have found. You may graph by hand or use your calculator to graph and copy and paste into the document.
