Question: (a) Make a table of values, rounded to two decimal places, for f(x) = log x (that is, log base 10) with x = 1, 1.5, 2, 2.5, 3. Then use this table to answer parts (b) and (c).
(b) Find the average rate of change of f(x) between x = 1 and x = 3.
(c) Use average rates of change to approximate the instantaneous rate of change of f(x) at x = 2.
