Let f : A -> B be a function defined by f (x) = (x/2) - 1 where A = {2, 4, 6, 10, 12}, B = {0, 1, 2, 4, 5, 9} .

Represent f by

(i) set of ordered pairs; (ii) a table; (iii) an arrow diagram; (iv) a graph

Solution :

(i) set of ordered pairs

f (x) = (x/2) - 1

Set of ordered pairs = {(2, 0) (4, 1) (6, 2) (10, 4) (12, 5)}

(ii) a table

(iii) an arrow diagram;

(iv) a graph
