Key Concepts

System of Linear Equations

When specific points are substituted into the quadratic function, they generate a system of linear equations in terms of the unknown coefficients. Solving this system—often through methods like substitution or elimination—yields the values of a, b, and c that tailor the function to the data.

Interpolation

Interpolation is the method of estimating a function that exactly passes through a set of known points. Here, it underpins the idea of determining a quadratic function that accurately reflects the provided coordinate pairs.

Quadratic Function

A quadratic function is a type of polynomial of degree two, typically expressed as y = ax² + bx + c. Its graph is a parabola that opens upward or downward depending on the sign of the coefficient a. Understanding the standard form of a quadratic function helps in analyzing its key features, like its vertex and axis of symmetry.

Curve Fitting

Curve fitting involves finding the parameters of a chosen mathematical model so that its graph best represents a set of data points. In this context, it means determining the coefficients of a quadratic function that passes exactly through the given points.
