What will I learn?
The General Concepts of Functions Course gives you a clear, practical toolkit for working with domain, codomain, image, and preimage, including implicit restrictions and interval preimages. You will master notation, composition, injectivity, surjectivity, and inverses through concrete linear, quadratic, and reciprocal examples, while also improving written explanations, error checking, and report-ready solution steps.
