Fitting Exponential Models to Data · Review Exercise 127

Enter the data from each table into a graphing calculator and graph the resulting scatter plots. Determine whether the data from the table would likely represent a function that is linear, exponential, or logarithmic.

$$\begin{array}{cc}\text{x}& \text{f(x)}\\ \text{0.5}& \text{18.05}\\ \text{1}& \text{17}\\ \text{3}& \text{15.33}\\ \text{5}& \text{14.55}\\ \text{7}& \text{14.04}\\ \text{10}& \text{13.5}\\ \text{12}& \text{13.22}\\ \text{13}& \text{13.1}\\ \text{15}& \text{12.88}\\ \text{17}& \text{12.69}\\ \text{20}& \text{12.45}\end{array}$$

Its source prints no answer for this problem, so there's nothing to check against.
