What is Quadratic Function in Math? A quadratic function is a polynomial function with one or more variables in which the highest exponent of the variable is two. In other words, a quadratic function is a “polynomial function of degree 2.”
In mathematics, a quadratic polynomial is a polynomial of degree two in one or more variables. A quadratic function is the polynomial function defined by a quadratic polynomial.
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, the function will be linear and not quadratic.
Key Points. A quadratic function is of the form. f (x) = a x 2 + b x + c. f (x)=ax^2+bx+c f (x) = ax2 +bx+ c, where a is a nonzero constant, b and c are constants of any value, and x is the independent variable. The solutions to a quadratic equation are known as its zeros, or roots.
Definition: Quadratic Function. A quadratic function is a function of the form f(x) = ax2 + bx + c, where a, b and c are real numbers with a ≠ 0. The domain of a quadratic function is (− ∞, ∞). The most basic quadratic function is f(x) = x2, whose graph is Figure 2.3.1.
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
In this section, we will explore the quadratic functions, a type of polynomial function. Quadratics commonly arise from problems involving areas, as well as revenue and profit, providing some interesting applications.
Definition 2.5. A quadratic function is a function of the form \(f(x) = ax^2 + bx + c,\) where \(a\), \(b\) and \(c\) are real numbers with \(a \neq 0\). The domain of a quadratic function is \((-\infty, \infty)\).

A quadratic function is a polynomial function of the second degree and has the following form: *f (x)=ax^2+bx+c* where *a,* *b,* and *c* are real numbers, and *a≠0.* Some examples of quadratic functions are: *f (x)=-2x^2+8x-5* *g (x)=x^2+3* *h (x)=6x^2* *y=2x-x^2* *v=-1+u^2+2u*
