Explanation & Answer
Thank you for the opportunity to help you with your question!
constant term is 4 with factors 1,2,4
the leading coefficient is 3 with factors 1,3
then rational roots test yields
+-(1,2,4)/(1,3)
=+-1/(1,3),2/(1,3),4/(1,3)
=+-1/1,1/3,2/1,2/3,4/1,4/3
=+-1,2,4,1/3,2/3,4/3

Grossmont College Doctor Dogs Diagnose Cancer by Sniffing It Out Story Discussion
Learn by DoingHere are the directions, grading rubric, and definition of high-quality feedback for the Learn by Doing discussion board exercises. ContextA newspaper story in Knight Ridder Newspapers described an experiment in an article with the headline “Doctor Dogs Diagnose Cancer by Sniffing It Out.”In the experiment researchers trained dogs to identify people with breast or lung cancer. The dogs were trained to lay down if they detected cancer in a breath sample. After the training, dogs sniffed different breath samples of people with and without cancer. Impartial observers watched the dogs and decided when the dog identified a person as having cancer. Researchers then revealed the condition of the person who gave the breath sample and determined if the dog had correctly identified the presence of cancer.The newspaper states, “The researchers blinded both the dog handlers and the experimental observers to the identity of the breath samples.”PromptExplain what the following sentence means. “The researchers blinded both the dog handlers and the experimental observers to the identity of the breath samples.”Explain why blinding in this experiment is important.

Algebra 2 Graph & Functions DVDs Question Answers
John makes DVDs of his friend’s shows. He has realized that, because of his fixed costs, his average cost per DVD depends on the number of DVDs he produces. The cost of producing x DVDs is given by 1. John wants to figure out how much to charge his friend for the DVDs without making a profit. How much should he charge for 100 DVDs in order to break even? What is the cost per DVD? 2. Suppose John makes more than 100 DVDs for his friend. Complete the table below showing his costs at different levels of production. Show all your work. 3. Graph the function C(x) from 0 ≤ x ≤ 30004. What happens to the cost per DVD? Why do you think this happens? Write a function D(x), that can be used to find the cost per DVD for any value of x
