Question

Repeat the prior problem but use a fit that includes a quadratic term (so four terms in total). Report new values of fit constants. Add two new rows to the table to show updated fit values and fit error. Plot the data (as symbols) and the two fits (as different line styles), with temperature on the horizontal axis and resistance on the vertical. Use fine spacing when plotting the equations (i.e., compute values of the fit at many more than the tabulated values of T). Make the plot have a professional appearance (e.g., label clearly the plot axes, provide a legend, use well-sized fonts). Finally, comment on the quality of the fit for each equation.
