Key Concepts

Quadratic Functions

A quadratic function is a second degree polynomial expressed in the form y = ax² + bx + c. The coefficients a, b, and c determine the parabola's shape, direction, and position on the coordinate plane. This form is fundamental in algebra for modelling parabolic relationships and studying their properties such as vertex, axis of symmetry, and intercepts.

System of Linear Equations

When a quadratic function is required to pass through specific points, substituting these points into the quadratic equation creates a system of simultaneous linear equations in terms of the coefficients a, b, and c. Solving this system using methods like substitution or elimination is essential to determine the unique quadratic curve that fits the given points.

Polynomial Interpolation

Polynomial interpolation is the process of determining a polynomial that exactly passes through a given set of data points. In the case of quadratic interpolation, three points are used to solve for the three coefficients of a second degree polynomial, ensuring that the resulting function fits the data precisely.
