`scatter_plot()`command. - Using the Sage Find Fit Command for Linear Regression Using
`find_fit()`to perform a linear regression. - Using the Sage Find Fit Command for Quadratic Regression Using
`find_fit()`to perform a Quadratic regression. - Using the Sage Find Fit Command for Exponential Regression Using
`find_fit()`to perform an exponential regression. - Using the Sage Find Fit Command for Logarithmic Regression Using
`find_fit()`to perform a logarithmic regression.
