Given the graph of an exponential function write its equation. Rewriting the exponential expression this way will allow you to simplify and solve the equation. Try to choose points that are as far apart as possible to reduce round-off error. LOGEST is the exponential counterpart to the linear regression function LINEST described in Testing the Slope of the Regression Line.
