The video introduces calculus as the study of change and motion [], emphasizing functions as its core building blocks. It explains that functions map inputs to outputs, visualizing this in 2D with the x-axis for inputs and the y-axis for outputs, which collectively form a graph. A key characteristic highlighted is that a valid function must exhibit either a one-to-one or many-to-one relationship between its inputs and outputs [-]. This foundational understanding of functions is presented as crucial before delving into the complexities of calculus itself.
