Suppose you have the following relation: R: A-A where A = {a, b, c, d, e) R= ( (a, b), (a, e), (b, e)) Determine if it is reflexive, symmetric, anti-symmetric, and transitive. %3D Answer:
Let X + 0, X| 2 2. Then (X, Tina) is not To -space. Select one: OTrue O False
Given X = R (set of real numbers). Determine the T(E) of the following: Note: (a,b) is an interval and not an ordered pair. 8. E= {{1}, {1,2}, {1,3}, {1,4}, {2,3,4}} 9. E= {{1}, (1,2), ({1,2}} 10. E= {(1,3), (-∞, 2), (0,00), (-∞0,4)}
A and B are sets of real numbers defined as follows. A= {w | w<4} B={w | w26} Write An B and A UB using interval notation. If the set is empty, write Ø. (0,0) [0,0) (0,0) AnB =| [0,0) OUO AUB = I - 00 8.
