In an experiment, the process is studied in a chemical process, in which a particular substance is formed. During the experiment Once the concentration c of the substance in question is measured at different times t. The table below shows some measurement values (in appropriate units, as we disregard this).

Sketch on a Matlab program that use least square approximation on a quadratic polynom to these data as well as draws a graph showing both the measurement points and the quadratic polynom. Use the Polyfit Matlab Commands and polyval. Here are the initial lines of the help texts of the boats:
