uiz 7. Name: Five questions, four points each, twenty points total. Please show your work! #1. Sketch a nice graph by applying transformations to the five amigos of the basic function: f(x) = 4 - log2(4 - x) #2. Combine into a single logarithm: log3x - 2 log3y + log9z #3. Solve for x, expressing your result in exact form (not some crummy decimal): 4x + 3 = 31 - x #4. Solve for x, expressing your result in exact form (not some crummy decimal): ln(x) + ln(5 - 2x) = 1 5. The population of the world was about 3.7 billion in 1970 and 6.8 billion in 2010. Assuming continued exponential growth, what will be the world population in the year 2070
