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.

Afarmer has a large field that is x feet in length. he wants to fence in a rectangular section in the middle of the field , leaving a length of 100 feet of open field behind each end of the fenced rectangle.he also wants the width of the fenced-in space to be 100 feet less than its length. find the expressions to represent the length and width of the fenced section of the field
