Question

Injective and subjective function meaning​

Answer 1

Answer:

❥Injective is also called "One-to-One" Surjective means that every "B" has at least one matching "A" (maybe more than one). There won't be a "B" left out. Bijective means both Injective and Surjective together. Think of it as a "perfect pairing" between the sets: every one has a partner and no one is left out.

Answer 2

Step-by-step explanation:

• A function is injective (one-to-one) if each possible element of the codomain is mapped to by at most one argument.
• Since every function is surjective when its codomain is restricted to its image, every injection induces a bijection onto its image.
