The video tutorial covers key mathematical concepts including domain and range, distinguishing between functions and relations, solving linear equations, and plotting points on a graph. It also explores quadratic functions and their graphical representations. The tutorial uses examples and visual aids to explain these concepts, ensuring a comprehensive understanding of the material.
