Homework SourseDefine function i by ix x1 for all x This function is inje
Define function i: by i(x) = [(x,1)] for all x . This function is injective. I don\'t understand if this is true or false
Solution
yes, This function is injective
because if i(x1) =i(x2)
=> [(x1,1)]= [(x2,1)]
=>x1=x2
there exists distinct values for distinct x
