Fitting Exponential Models to Data · Exercise 50

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 intersect feature to find the value of $x$ for which $f\left(x\right)=8.$
