6.8 Exercise 70

Use a graphing utility to find an exponential regression formula $f \left(x\right)$ and a logarithmic regression formula $g \left(x\right)$ for the points $\left(1.5 , 1.5\right)$ and $\left(8.5 , \text{8}.\text{5}\right) .$ Round all numbers to 6 decimal places. Graph the points and both formulas along with the line $y = x$ on the same axis. Make a conjecture about the relationship of the regression formulas.
