Algebra encompasses a range of mathematical concepts, and linear functions and quadratic equations are fundamental components of algebraic study. Linear functions represent relationships with a constant rate of change, often seen in the form of the equation y = mx + b, where m is the slope and b is the y-intercept. These functions form the basis for understanding more complex systems. Quadratic equations, characterized by the general form ax² + bx + c = 0, represent polynomial functions of degree two and are crucial for exploring topics like parabolas, roots, and vertex form.

While other areas of mathematics such as trigonometry, calculus, graph theory, and matrix operations have their own significance and applications, they do not primarily fall under the umbrella of algebra. For instance, trigonometric ratios are mainly involved in the study of triangles, and calculus introduces concepts of limits and derivatives. Similarly, graph theory and statistical analysis involve distinct methodologies and applications that go beyond algebra. Therefore, linear functions and quadratic equations accurately represent the core topics commonly included in algebra.
