Fitting Exponential Models to Data · Exercise 40

Refer to the table.

$$\begin{array}{ccccccc}\text{x}& \text{1}& \text{2}& \text{3}& \text{4}& \text{5}& \text{6}\\ \text{f(x)}& \text{555}& \text{383}& \text{307}& \text{210}& \text{158}& \text{122}\end{array}$$

Use the intersect feature to find the value of $x$ for which $f\left(x\right)=250.$
