Can someone please tell me how do I do this question? I know that the first one cannot be calculated but I still don’t know how to do the rest.

Thank you so much!

2. Consider the mappings L . M, N , and P given in the previous question . For each of the following compositions ."- Determine if it is defined ( meaning , check if the codomain of the mapping on the right is the domain ofthe mapping on the left , so that the composition is defined ) .If it is defined :- State its domain and codomain .- Determine if the mapping is linear : if it is prove this , otherwise explain why it is not linear .- If the mapping is linear find its standard matrix .( 2 ) LOL( b) NOL( C ) POM( d ) NOM
