Homework 23

Read: Finish Section 7.1 and start 7.2.

Turn in: 7.29, any 8 parts of 7.34 (see modified directions below), 7.36, 7.37, 7.39 (same 8 parts as you did for 7.34)

• For 7.29, you should be writing out a set of ordered pairs for each of $R$, $S$, and $T$.
• For 7.34, I’m simplifying the directions: if a relation is not reflexive, symmetric, or transitive, please give a counterexample showing why, but if the property holds, you do not need to give a proof.
