Here is an easy way to remember which is which:
Injection: 1nject
1ion, i.e. 1-to-1
Surjection: as the word "sur" means "on" in French, "surjective" means that the domain A is mapped onto the codomain B, i.e. the whole codomain is covered by the image of the domain.
Bijection: as the prefix "bi" means "two", "bijective" means a function that has
both properties: is both injective and surjective
