Web22 nov 2024 · To show a function is injective, you want to show that If f ( x) = f ( y) then x = y So let h ( x) = h ( y) Then x 3 = y 3 and when we cube root each side we get x = y. Therefore it is injective To show a function is surjective, for any element in the codomain we have to show their is an element in the domain that maps to it.

WebNote that unlike injective, surjective, bijective, this is a predicate defined on the domain of a relation. Another way of seeing this is that when we look at the bipartite graph of the relation, if every element on the domain side has out degree exactly one, then we call the relation a function.

It follows from b = 3 being odd that g(a) 6= b for any a 2Z because of di erent parity. Hence, g is not surjective, and therefore, not a bijection.

WebA surjection, or onto function, is a function for which every element in the codomain has at least one corresponding input in the domain which produces that output. A function that is both injective and surjective is called bijective.
