Use a graphing utility to find an exponential regression formula f ( x ) and a logarithmic regression formula g ( x ) for the points ( 1.5 , 1.5 ) and ( 8.5 , 8.5 ) . 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.
