Let \(f: A \rightarrow B\) be a function defined by \(f(x) = \frac{x}{2} - 1\), 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
Ans:
Function as set of ordered pairs:
Answer variants:
\(\{(2, 0), (1, 1), (3, 2), (6, 4), (14, 5)\}\)
\(\{(2, 0), (4, 1), (6, 2), (10, 4), (12, 5)\}\)
\(\{(2, 0), (4, 2), (6, 3), (10, 5), (12, 4)\}\)
