Extracted text: For each of the following mappings indicate what type of function they are (if any). Use the following key: i. Not a function ii. A function which is neither onto nor one-to-one iii. A function which is onto but not one-to-one iv. A function which is one-to-one but not onto A function which is both onto and one-to-one V. Clearly indicate in the text box below which choice you've made from the options above for each of the parts below. (a) mapping f from Z to N defined by f(n)= |2n|. (b) mapping f from {1, 3} to {2, 4} defined by f(n) = 2n. (c) The mappingffrom R to R defined by f(n)= 8–2n. (d) The mapping ƒ from R to Z defined by f(x) = [x+1] (e) The mappingf from R+ to R+ defined by f(x) =x – 1.
