how to prove a surjective function
Let us take a look at the function f:R→[−1,1] defined by f(x)=xx2+1. Recall that a function f is injective if f(x)=f(y)⟹x=y. With this in mind, we ...,Let's do it for special case A⊂S=N. Starting with f=idN it comes to defining h(n) inductively as the smallest integer in A−h(1),…,h(n−1)}. Since A is infinite this set ... ,A General Function points from each member of "A" to a member of "B". It never has one "A" pointing to more than one "B", so one-to-many is not OK in a function ... ,To prove that a function is surjective, take an arbitrary element y∈Y and show that there is an element x∈X so that f(x)=y. I suggest that you consider the equation f(x)=y with arbitrary y∈Y, solve for x and check whether or not x∈X. , , To prove that a function G:Ato B is not surjective, simply argue that some element of B cannot possibly be the output of the function G .
