Fitting Exponential Models to Data · Exercise 47

Refer to the table.

$$\begin{array}{ccccccccc}\text{x}& \text{1}& \text{2}& \text{3}& \text{4}& \text{5}& \text{6}& \text{7}& \text{8}\\ \text{f(x)}& \text{7.5}& \text{6}& \text{5.2}& \text{4.3}& \text{3.9}& \text{3.4}& \text{3.1}& \text{2.9}\end{array}$$

Use the LOGarithm option of the REGression feature to find a logarithmic function of the form $y=a+bln\left(x\right)$ that best fits the data in the table.

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