The inches of rainfall on Mount Wai'ale'ale on Kauai in Hawaii is represented by the function f(x) = 3x+1 - 22. Scientists are using this equation to study the amount of
rainfall from year to year.
a) Calculate how much rainfall there was in year 4 and in year 9. You must show all
your work and explain each step.
