Problem 2. Let V = span{e3, e-3z}, and let the linear transformation D : V → V be differentiation with respect to x. One basis of V is C = {cosh(3x), sinh(3x)}, where e3z + e-3z e3z – e-3z cosh(3x) sinh(3r) %3D 2 The matrix of D with respect to C is A = 3 (a) Find the eigenvalues X1, X2 of A, and corresponding eigenvectors u (b) Explain what happens when we apply D to the elements u1 cosh(3x)+u2sinh(3x) and vị cosh(3x) + v½ sinh(3x) of V. 2.

y = demand for the large bottle of Fresh in the sales period(Demand)x1 = the price of product 1x2 = the price of product 2x3 = the advertising expenditure for Freshx4 = the price difference in the sales periodAdver = types of advertising campaignsCampaign A consists entirely of television commercials, campaign B consists of a balancedmixture of television and radio commercials, and campaign C consists of a balanced mixture oftelevision, radio, newspaper, an dmagazine ads. To ultimately increase the demand for Fresh,Enterprise Industries’ marketing department is comparing the effectiveness of three differentadvertising campaigns. To compare the effectiveness of advertising campaigns A, B, and C, wedefine two dummy variables. Specifically, DB is 1 if campaign B is used and 0 otherwise, DC is1 if campaign C is used and 0 otherwise. Our proposed model is  y = β0 + β1x4 + β2x3 + β3x 2 3 + β4x4x3 + β5DB + β6DC
