Some functions, such as the exponential or logarithmic functions, can be transformed so that they are linear. When so transformed, standard linear regression can be performed but must be applied with caution: Some nonlinear regression problems can be moved to a linear domain by a suitable transformation of the model formulation.

The student will determine numerous ordered pairs that satisfy a given logarithmic function, reverse the x and y coordinates, and use regression to determine the function that represents the inverse of the given logarithmic function. The student will then use this relationship to solve problems. Key Words
