Question
Please see attached photo. Im not sure how to use the properties of isomorphism to prove the composite function is 1-1, onto, and has the homomorphism property.
Expert Solution
Step 1
Since, phi is an isomorphism, it is one-one onto homomorphism. Thus, it is bijective. Similarly, Ψ is bijective. Hence, their composition is bijective.
