Algebra True or False? If false, give a counterexample. 1. For all sets S and T, SUT=SUT. 2. The following is a tautology: p-→q+(pAq). 3. For all functions f:A - B and g:B+ C, ifgf is one-to-one, then g is one-to-one. 4. If R is an equivalence relation on a set A, then the equivalence classes of R form a partition of A.

how to form solution to identify if they are reflexive, symmetric, antisymmetric, and/or transitive? thanks.
please send handwritten solution Q12 complete
4. Let A = {1,2,3} and B ={6,8,10} and define a relation R from A to B as follows: For all (x,y) € A x B, (x, y) ER means that is an integer. a. Is 2 R 8? b. Is 3 R 6? c. Is (3,10) E R? d. Is (1,6) € R? Write R as a set of ordered pairs. f. Write the domain and the range of R? g. Draw an arrow diagram for R.
A = {1, 2, 3, 5} and B = {4, 6, 9}. Define a relation R from A to B by R = {(x, y): the difference between x and y is odd; x ∈ A, y ∈ B}. Write R in roster form.
Need help with this math problem. I received feedback from my Professor for this homework problem and he said Connex? I think he meant connex relation. Below the homework problem is my work.

prove why each relation has or does not have theproperties: reflexive, symmetric, anti-symmetric, transitive. 1) Let A = { set of all people }, relation R: A x A where R = { (a,b) | a,b ∈ A, a is at least as tall as b }
