To represent a function graphically, we find ordered pairs that satisfy function rule, plot them, and then connect them in a smooth curve.
If A = {1, 2, 3}, B = {0, 1, 2, 4, 6, 8} and f: A→B be a function defined by f(x) = 2x. Represent this function as a set of ordered pairs.
If A = {1, 5, 6}, B = {4, 8, 9} and f : A→B is a function defined by f(x) = x + 3, represent the function as a set of ordered pairs, table form and arrow diagram.
