Let A = { 6, 9, 15, 18, 21 }; B = { 1, 2, 4, 5, 6 } and f : A → B be defined by

. Represent f by

(i) an arrow diagram

(ii) a set of ordered pairs

(iii) a table

(iv) a graph.

Given A = { 6, 9, 15, 18, 21 }

B = { 1, 2, 4, 5, 6 } and f : AB

And

We can find the domain

(i) an arrow diagram

(ii) a set of ordered pairs

From the given data and function value we can write the function as set of order pair as follows

f(x) = {(6,1),(9,2),(15,4),(18,5),(21,6)}

(iii) a table

From the data we can draw the tabular representation taking X and f(X)

(iv) a graph.

We can represent the function values in graph as follows

f(x) = {(6,1),(9,2),(15,4),(18,5),(21,6)}
