Let A = {o, c, e, a, n} and B define functions having the following properties and explain why the properties hold, or explain why it is impossible to have such a function. To define a function f (x), specify the images for each of the five elements of the domain using the form f(a)-?. 4. {n, i, g, h, t]. Using A as the domain and B as the co-domain, A function that is neither injective nor surjective. (Equivalently, a function that is not injective and is also not surjective) a. b. A function that is surjective but not injective. c. A function that is injective but not surjective
