Discrete math question
consider functions f : {1,2,3,4}→{1,2,3,4,5,6}.
a) give an example of one such function (use 2-line notation). then say how many such functions there are and why your answer makes sense.
(b)give one example of such a function that is injective and one that is not. then say how many injective functions there are and why your answer makes sense.
(c) explain why there are no surjective functions with this domain and codomain.

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
