(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

f: B => C and g: A => B

1. If f of g is injective, then f is injective.

2. If f of g is injective, then g is injective.

2. Relevant equations

3. The attempt at a solution

I know that 1 is true and 2 is false because I found those as properties, but I am not exactly sure why, and I do not know how to show a proof.

Any help please?
