Let {el, e2, es} be the standard basis of RS. If T : I* > IR* is a linear transformation such that 0 2 T(el) = 2 T(e2): 4 , and T(e3) = -2 4 -3 then T( 4 ) = 04 -12 48 Let A = 15 -18 and b = 69 8 30 A linear transformation T : R* - R* is defined by T(x) = Ax. C1 Find an x = in IR whose image under T is b. T2 C1
