Let A = {4, 5, 6} and B = {5, 6, 7} and define relations R,
S, and T from A to B as follows:
For all (x, y) ∈ A × B,
(x, y) ∈ R means that x ≥ y.
(x, y) ∈ S means that
x − y/ 2
is an integer.
T = {(4, 7), (6, 5), (6, 7)}.
a. Draw arrow diagrams for R, S, and T .
b. Indicate whether any of the relations R, S, and T are
functions.

Best ResponseYou've already chosen the best response.2A X B is a set of all ordered pairs (x,y) such that x is in A, y is in B what I like to do is make a table that is 3x3. 3 rows because there are 3 elements in B 3 columns because there are 3 elements in A along the top, I put the elements of set A along the left side, I put the elements of set B dw:1443397063622:dw

Best ResponseYou've already chosen the best response.2actually it might be better to swap the places of A and B dw:1443397190016:dw

Best ResponseYou've already chosen the best response.2to fill out this table, we simply list the points (x,y) where x comes from A, y comes from B eg: (4,5) goes in the top left because we have 4 from A, and 5 from B dw:1443397266909:dw
