For each of the following sets, say whether or not they are linearly independent. Justify your answer for each. A. B. C. 2 4 1 1 3 6 2 { [²] [ 7 9 - 4 -2 3 0 0 0 6 1 -1 4 -5 0 A}

I. TRUE OR FALSE. Write 1 if the statement is always true. Otherwise write 0. 8. For any sets A, B, we have A – B = (B – A)'.

Determine the domain and range of each of the following relations. Use listing method for items 1 and 2, set builder notation for items 3 and 4, and interval notation for items 5 and 6. 1.
