WebNotice that in the deﬁnition of “onto”, we need to know what the codomain is. So the function f = {(x,ex) : x ∈ R} is not onto when thought of as a function from R to R, but it is onto when thought of as a function from R to (0,∞). Proposition 4. Let f : A → B be a function. Then f is an onto function from A to Ran(f). If f is WebInjective is also called " One-to-One ". Surjective means that every "B" has at least one matching "A" (maybe more than one). There won't be a "B" left out. Bijective means both Injective and Surjective together. Think of it as a "perfect pairing" between the sets: every one has a partner and no one is left out.

Set theory is the branch of mathematical logic that studies sets, which can be informally described as collections of objects. Although objects of any kind can be collected into a set, set theory, as a branch of mathematics, is mostly concerned with those that are relevant to mathematics as a whole.
