Access to several mobile phon... estion 1: a) Let O be the set of odd numbers and O' = {1,5,9, 13, 17, ...} be its subset. Define the bijections, f and g as: f: 0-O', f(d) = 2d - 1, Vd 0. g:N-0, g(n) = 2n + 1, Vn N. Using only the concept of function composition, can there be a bijective map from N to O'? If so, compute it. If not, explain in details why not. [2+8) b) Using the congruence modulo relation, write 17. i) in base 4 ii) in base 3 [(5)+(5)]
