Let f:G→ H be a homomorphism of groups and let K be a subgroup of H.Prove that the set {aɛG|f(a)EK} is a subgroup of G.31. If f:G→ Gis a homomorphism of groups, prove that F= {aEG|f(@) = a} isa subgroup of G.(:)32. If A =is a matrix, the number ad - be is denoted det A and calledthe determinant of A. Prove that the function f:GL(2, R)→R* given by= det A is a surjective homomorphism.33. Let f:G→ H be a homomorphism of groups and let K,= {aeG|f(a) = en},that is, the set of elements of G that are mapped by fto the identity elementof H. Prove that K, is a subgroup of G. See Exercises 34 and 35 for examples.34. The function f.Z→Z, given by f(x) = [x] is a homomorphism by Example 13.Find K(notation as in Exercise 33).11:22 AMEPICO Type here to searchAiEPIC5012/11/2020
