Smartphone users, as a percentage of the population, are projected to be f(t) = 18.952 + 14.088 ln(t + 1)    (0 ≤ t ≤ 5) percent in year t, where t is measured in years, with t = 0 corresponding to 2010. What is the projected average percentage of the population that will be smartphone users over the period from 2010 through 2015?† (Round your answer to three decimal places.)

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
