A quadratic function is a polynomial of degree 2 and so the equation of quadratic function is of the form f(x) = ax 2 + bx + c, where 'a' is a non-zero number; and a, b, and c are real numbers. What is the Vertex of Quadratic Function?
Quadratic functions & equations - Khan Academy
We've seen linear and exponential functions, and now we're ready for quadratic functions. We'll explore how these functions and the parabolas they produce can be used to solve real-world problems.
5.1: Quadratic Functions - Mathematics LibreTexts
Jan 16, 2020 · In this section, we will investigate quadratic functions, which frequently model problems involving area and projectile motion. Working with quadratic functions can be less complex than working with higher degree functions, so they provide a good opportunity for a detailed study of function behavior.

Quadratic function. A quadratic is a polynomial where the term with the highest power has a degree of 2. The parent function of quadratics is: f(x) = x 2. Quadratic functions follow the standard form: f(x) = ax 2 + bx + c. If ax 2 is not present, the function will be linear and not quadratic. Quadratic functions make a parabolic U-shape on a graph.
