List the ordered pairs shown in the mapping diagram.
From the above diagram, we can see a well-defined one-to-many mapping from the domain {1,3,5,7} onto the range {8,6,4,2}.
Here, input is domain and output is range.
Hence, the ordered pairs are (1,8)(3,8)(3,4)(5,6)(7,2).
Is the following set of ordered pairs function?
If so, examine whether
the mapping is injective or surjective. {i} {(x,y): x is a person, y is the mother of x } {ii} {(a,b):a is a person, b is an ancestor of a }
Are the following set of ordered pairs functions? If so examine whether the mapping is injective or surjective. (ii){(a,b):a is a person, b is the ancestor of a}.
