Extracted text: 2). For the following linear transformations T: R → R², where Ti(r, y) = (2x + 3y, 5x – y) T2 : R → R², where T2(r, y) = (3x + y, x – 3y) a). Show that T1 and T2 are one-to-one and onto. b). Find formulas for T (x, y), T,'(r, y) and (T2 o T1)-'(x, y) c). Check whether that (T2 o T1)- = T¡' o T,'.
