Functions: Injections and Surjections

Covers the generalities of functions, including the definition of an application between sets and the uniqueness of elements in the image set.

Covers applications between sets, functions, and graphs, exploring injectivity, surjectivity, and bijectivity.

Covers the basics of functions, including domain, codomain, image, and range, as well as injections, surjections, and bijections.

Explores the relationships between functions and sets, focusing on composite functions properties.

Introduces sets and functions, covering union, intersection, complement, functions terminology, and set operations analogies.
