Question

Name 6 category of funtion in funtion library

Answer 1

Answer:

These properties concern the domain, the codomain and the image of functions.

Explanation:

   Injective function: has a distinct value for each distinct argument. Also called an injection or, sometimes, one-to-one function. In other words, every element of the function's codomain is the image of at most one element of its domain.

   Surjective function: has a preimage for every element of the codomain, that is, the codomain equals the image. Also called a surjection or onto function.

   Bijective function: is both an injection and a surjection, and thus invertible.

   Identity function: maps any given element to itself.

   Constant function: has a fixed value regardless of arguments.

   Empty function: whose domain equals the empty set.

   Set function: whose input is a set.

   Choice function called also selector or uniformizing function: assigns to each set one of its elements.
