Line 54: *''f'' is a[n] '''[[Injective function\|Injection]]''' if the ___domain of ''f'' is ''A'' and the range of ''f'' is a subset of ''B''. Am I missing something? This condition does not seem to restrict the function f in any way. (f(x)=0 would meet the definition, if 0 is an element of B.) - [[User:Mike Rosoft\|Mike Rosoft]] ([[User talk:Mike Rosoft\|talk]]) 19:55, 5 July 2012 (UTC) :This is a mistake.—[[User:EmilJ\|Emil]] [[User talk:EmilJ\|J.]] 15:10, 9 January 2013 (UTC)
