Suppose a patient requires a 30-milligram dose of Sneeze-BGone. Use home screen recursion on your calculator to fill in the table. 2. At what value does the amount of Sneeze-B-Gone in the bloodstream level off? How many days does it take for that to happen? It levels off at 99.951 and takes about 20 days 3. How does the function rule for the 20-milligram dose change for a 30-milligram dose? Write the new function rule for the portion of the graph between Day 1 and Day 2. Day 1: 20*.8+20DayMilligram120226 4. How do you think those changes would affect the graph of the new function rule? 5. Use your graphing calculator to test your prediction. Sketch your graph.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
