Quiz # 2 Review Sheet:

The quiz on Monday will consist of definitions, and will be brief. Your wording on a definition must be precise, and you will be required to give both a symbolic form and a verbal interpretation of the symbols. (Recall that an interpretation is a conceptual translation, not a symbol-by-symbol transliteration.) You may be asked to produce examples or verify that something satisfies the requirements of a definition. The ideas you should know include:

f\colon X \to Y
f^{-1}\colon Y \to X
f\circ g
f is one-to-one
f is onto
f is a bijection
{\rm id}_X

R is a relation on X
R is reflexive
R is symmetric
R is transitive
\equiv is an equivalence relation on X
