Problem 2 Given 171 data points (31,33), ($2,192), . . . , (Im,ym]. We want to t an exponential function y = (:0 - (3'31\" to these data points. When we plug in the data points to the functions wc want to t, we obtain a systcm of nonlinear equations with variables en, (:1 (so we cannot use least squares method). The goal of this problem is to use some trick to make the least squares method applicable. a/ Perform necessaly transformation (hint: taking 111) to change this into a least square problem A3: = b. b/ Derive the formula for the least squares solution ((30,61)
