only need part A and B solution as soon as possible

Step 4: Fitting an exponential function. Next, we want to t an exponential function y = co - e\": to these data points. When we plug in the data points to the mctions we want to t, we obtain a system of non-linear equations with variables no, C; (so we cannot use least squarai method). The goal of this problem is to use some trick to make the least squatm method applicable. a/ Perform necmary transformation (hint: taking In) to change this into a least square problem A: = b. Math 311 Optional Projects 2 LINE AND CURVE FITTHVG b/ Find the least squares solutions (Bio, 61) and the best t exponential function. Remember to include your works. cf Plot both the data points and the exponential function on a graph
