If T1(x) and T2(x) are onto linear transformations from Rn to Rm, then so is w(x) = T1(x) + T2(x) True, by the definition of linear transformation. True, by the definition of linear transformation and the definition of onto. False. Consider T2(x) = T1(x), where T1 is onto. False. Consider T2(x) =-T1(x), where T1 is one-to-one False. Consider T2(x) =-T1(x), where T1 is onto
