Hello, I need some help. Could someone kick me(hard please) in the right direction here? Here are the statements I need to prove:(adsbygoogle = window.adsbygoogle || []).push({});

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

2) If g of f is subjective, then g is subjective

where g and f are functions where f:A->B and g:B -> C where A,B and C are sets

Any kicks in the right direction would be GREATLY appreciated. Thank you.
