A quadratic function is a polynomial function with one or more variables in which the highest exponent of the variable is two. Since the highest degree term in a quadratic function is of the second degree, therefore it is also called the polynomial of degree 2.
In mathematics, a quadratic function of a single variable is a function of the form [1] = + +,, where is its variable, and , , and are coefficients.

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 ax2 is not present, …
2020年1月16日 — Definitions: Forms of Quadratic Functions. A quadratic function is a function of degree two. The graph of a quadratic function is a parabola. The general form of a quadratic function is f(x) = ax2 + bx + c where a, b, and c are real numbers and a ≠ 0. The standard form of a quadratic function is f(x) = a(x − h)2 + k.
The cross-section of the antenna is in the shape of a parabola, which can be described by a quadratic function. In this section, we will investigate quadratic functions, which frequently model problems involving area and projectile motion.
Quadratic Equation in Standard Form: ax 2 + bx + c = 0; Quadratic Equations can be factored; Quadratic Formula: x = −b ± √(b 2 − 4ac) 2a; When the Discriminant (b 2 −4ac) is: positive, there are 2 real solutions; zero, there is one real solution; negative, there are 2 complex solutions
