how would I express the range of each function using roster notation?

(b) Let A = {2,3,4,5) f. A Z such that f(x) = x2 (c) 0:{0,115-Z For x = {0,1),f(x) is the number of times '01' occurs in the string. For example f(01101) = 2 because the string '01" occurs twice in "01101". The first occurrence starts at the first bit. The second occurrence starts in at the fourth bit Solution f: (0,1)5 - Z. For x (0.1) f(x) is the number of 1's that occur in x. For example f(01101) = 3, because there are three 1's in the string *01101" f(0,119 (0.1) For x E 10.118 f(x) is obtained by replacing the last bit with 1. For example f(000) = 001, (1) Let A = 12,3,4,5) FAXA - Z where f(x,y) = x+y. (9) Let A = {1,2,3) f: AxA - Z where f(x,y) = x (h) Let A = {1,2,3) fAXA-ZZ where fxy) = (y,x) 0 Let A = (1,2,3) fAXA - Z Z where f(x.y) = (xy+1). 1 Let A = (1,2,3)
