1. Consider the relation < on the set {1,2, 3, 4}. Write down this relation as a set of ordered pairs in roster form.

1. Let A = {0, 1,2,3,4,5). Write out the relation R that expresses > on A. Then illustrate it with a diagram. 2. Let A = {1,2,3,4,5,6). Write out the relation R that expresses | (divides) on A. Then illustrate it with a diagram. 3. Let A = {0, 1,2,3,4,5). Write out the relation R that expresses ≥ on A. Then illustrate it with a diagram.

R= {(1,2), (1,3), (1,4), (2,3), (2,4), (3,4)} is a relation on the set A = {1, 2, 3, 4}. 3.a. Show the digraph of R. 3 b. Show the matrx of R. 3.c. Determine whether R is reflexive, symmetric or transitive. You must give reasons for these answers. 100%

6. Create a table of values for each relation with a minimum of 4 points. Graph each pair of relations on the same set of axes. Fully label your graphs 2x a) y = (²-)* and y= v = (-²) b) y = 4* y = 4(5) and y
