Fitting Exponential Models to Data · Exercise 45

Refer to the table.

$$\begin{array}{ccccccc}\text{x}& \text{1}& \text{2}& \text{3}& \text{4}& \text{5}& \text{6}\\ \text{f(x)}& \text{5.1}& \text{6.3}& \text{7.3}& \text{7.7}& \text{8.1}& \text{8.6}\end{array}$$

Use the intersect feature to find the value of $x$ for which $f\left(x\right)=7.$

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