Let A = {12, 13, 14, 15, 16, 17} and f:A→Z be a function given by f(x) = highest prime factor of x.
(i) Find the domain of the function f(x)=x2+2x+1x2−8x+12.
(ii) Let A={8,11,15,12,15,18,23} and f be function from A→N, such that f(x) is the highest prime factor of x. Find f and its range.
Let A = {9, 10, 11, 12, 13} and let f: A → N be defined by f(n) = the highest prime factor of n. Find the range of f.
