The video tutorial explains the concept of a function as a mathematical relationship where each input has exactly one output. It uses a sequence to demonstrate this concept, showing that each input in the sequence results in a single output. The vertical line test is introduced as a method to verify if a graph represents a function. The tutorial concludes by stating that all sequences are functions because they adhere to the one input, one output rule.
