You can obtain the equations for exponential, power, and logarithmic regression curves by linearizing the functions. For example, the equation y = ac x can be linearized by taking the natural logarithm of both sides. Doing this yields Ln (y) = Ln (a) + Ln (c)x. This is now linear in the variables Ln (y) and x.
