Textbook Question
Chapter 3.1, Problem 85PE
Make Sense? In Exercises 83-86, determine whether each statement makes sense or does not make sense, and explain your reasoning.
Taxing thoughts: I'm looking at data that show the number of pages in the publication that explains the U.S. Tax code for selected years from 1945 through 2013. A linear function appears to be a better choice than an exponential function for modeling the number of pages in the tax code during this period.
