A 17 maria Suppose that you were asked to use the least squares method to find a parabola that hits the four sample points (-2,1).(1,3).(4-1) and (-1,2) That is to ind a quadratic polynomialy +0+02 that best describes the given data in your handwritten work, astus the linear system of cowtionszand the contes conditmatrix form. Vay that you would solve to find the coethdents of the desired quadratic polynomial. Remember in your lectore notes, we referred to matrix the Vandermonde mat. Youneed to contract our liceansystem and its matris form and clearly.bel your matrie V. column vectors and y Show All your work Yuda. NOT need to solve the system PGB B. (4 marto) Suppose that you were to determine a curve of the form Y exp AX+B that hits a table of prescribed (X,Y) values where X and Y are non negative numbers. Write down the lineatization that you would apply to find your new variables to solve this problem. Male sure you clearly show your new variables, and in your in terms of the old variables X,Y A and B Show All your steps Note that you only need to do the linearization and you Do NOT to compute any numerical values
