I have 2 data sets that determine a y-value based on known x-values (the x-values are given as temp degrees C) ---- each of those actual line graphs have been fitted with an approximate "best fit" line determined by Excel with 2 separate 6th order line equations.
Our homework asks us to add the 2 polynomial equations together and then determine the calculated y-values for each of the known x-values shown (temperature) and then plot that line on the attached graph.
Show me how to add the 2 polynomials and then provide me the math that will calculate the resultant polynomila given the known x-values.
The solution file is attached.
Please note the following with regard to this work:
(1) As per your instructions, I have just added the two polynomial equations and graphed the resulting equation. I have also provided the Table of values (Temp, Heat ...
Elaborate discussion regarding how to go about obtaining the sum of two sixth order polynomial line equations is included.
