WebFeb 23, 2013 · The contrapositive method allows us to use our algebraic skills in a straightforward way. Next let’s prove that the composition of two injective functions is injective. That is, if f: X → Y and g: Y → Z are injective functions, then the composition g f: X → Z defined by g f ( x) = g ( f ( x)) is injective.

WebFeb 9, 2014 · Thus, proving that "if n is odd then n 2 is odd" is contrapositive of the statement that "if the square of a number is even then the number itself is even" rather than the statement you cited. To show the contrapositive, assume n is odd so that n = 2 k + 1. Then n 2 = 4 k 2 + 2 k + 1 and therefore also odd, q.e.d. Share. WebFor example, A\(\rightarrow\)B.
