Use the last digit of your phone number and create a Set A with that number of elements. Write your set using Roster Form. Identify the cardinality of your Set A using the correct notation. Identify the number of subsets and proper subsets of your Set A. Write a sentence or paragraph explaining the difference between the number of subsets and proper subsets. Last Digit 3
Are the following subsets subspaces of the given vector space?Justify your answers using words and proper mathematical notation. If the set is not a subspace of the given vector space, give a counterex- ample (an example that demonstrates that one of the axioms fails) and explain why this shows the subset is not a subspace. If the set is a subspace, then prove it by showing that the conditions for a subset to be a subspace are met (a) S...
