Learning Goal: I’m working on a computer science question and need the explanation and answer to help me learn.
I have five questions I need an answer for please
1) Define a relation S from R to R as follows:
For all (x, y) R R,
(x, y) S means that x y.
a. Is (2, 1) S? Is (2, 2) S? Is 2 S 3? Is (1) S (2)?
b. Draw the graph of S in the Cartesian plane.
2) 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
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.
4) Let A = {1, 0, 1} and B = {t, u, v, w}. Define a function
F: A B by the following arrow diagram:
a. Write the domain and co–domain of F.
b. Find F(1), F(0), and F(1).
