Is this call explanation???

[@user-gw3ct3xs9u]

Thanks for this brilliant explanation

[@hakeemadejare4818]

Sincerely speaking, you have really done a very good job indeed. Kudos to you❤ .But sir,the one-one definition you used in your explanation should have been "if f(x1)=f(x2) then x1=x2" and not f(x1)≠f(x2) then x1≠x2.
I hope I am correct??

[@upprrdimensions892]

Both are actually correct. You can use either one process

[@user-m_u_s_k_a_n]

Thnx sir for the explanation ❤

[@FountainofMathematics]

Always welcome

[@nishith_shettigar_belma]

Your are not explaining the terms properly man

[@hakeemadejare4818]

What of his solution sir?
I think he should have used " if f(x1) =(fx2) then x1=x2 instead???
