Learning the general shapes of some common function families can be helpful
in analyzing various problems. This can also be helpful in applying the ideas of
statistical regression. Statistical regression typically gathers a collection of data
points and tries to fit a mathematical function to the data points. Choosing the
type of function that will best fit the data is an important step in determining a
suitable regression function.
