. Let n≥1. For each A∈GLn(R) and b∈Rn, define a map [A,b]:Rn→Rn by [A,b](x)= Ax+b for all x∈Rn. Such transformations of Rn are called invertible affine transformations of Rn. Let Affn={[A,b]:A∈GLn(R),b∈Rn} 1. Prove that Affn is a group with respect to composition. 2. Prove that the subset T={[In,b]:b∈Rn}⊂Affn is a normal subgroup Aff . . . . 3. Describe the quotient group Affn/T.
