(1 point) let uz = (1,2,1), u, = (2,5,2), ug = (4,8,5). (a) find the transition matrix corresponding to the change of basis from the standard basis b = {(1,0,,1,,0,1)} to b' = {u1, u2, u3}. (b) find the coordinate vector of each of the following vectors with respect to b' = {ui, u, u3}. remember to enter your response as a vector using angular brackets. (i) x = (2,0, -3), x]b = | (1) x= (1,1,1), xe = (iii) x = (0,1,0), x]b =
