Given,
The equation is,
The given equation is in form of ab^x.
On comparing the given equation with this equation, we get,
The conversion of the equation in form e is,
Substituting the value of a and b in the equation then,
Hence, the equation y in form of e is y=2.6e^((ln 0.9)x) or y=2.6e^(-0.105x).
