2 Consider the set A={-2, -1,0, 1, 2}. For each relation a to c: i List all the ordered pairs (x, y) that represent this relation.
ii Hence, list the elements of the range (set B).
iii Draw a mapping diagram to represent the relation between set A and set B.
iv Use your mapping diagram to determine which type of relation it is.
Determine whether or not the relation is a function.
a y = x
by= 3x + 3
c y=x²
