Discussion:
Given:
All students at a university have a mentor.
A. Explain why the given described is an onto mapping.
B. Create a own real-world example of an onto mapping without using a math formula
o Explain what set constitutes the domain.
o Explain what set constitutes the codomain.
o Explain what relationship exists between the elements in the domain and the elements in the range.
C. Explain how we could change the domain of the mapping in part B so that the mapping would no longer be onto.
D. Explain how we could change the codomain of the mapping in part B so that the mapping would no longer be onto.
