That is, in a quadratic function, the highest power of x (or the variable of interest) is 2. Put more formally, we can write a quadratic function like this: f(x)=ax2+bx+c where a≠0, and b and c are real numbers
Aquadratic functionis defined as a polynomial where the highest degree of any variable is 2. In other words, a term in the equation will have an exponent to the power of 2. An equation such a {eq}f(x) = x^2 + 4x -1 {/eq} would be an example of a quadratic function because ...
Standard form: f(x) = ax2 + bx + c, where a ≠ 0. Vertex form: f(x) = a(x - h)2 + k, where a ≠ 0 and (h, k) is the vertex of the parabola representing the quadratic function. Intercept form: f(x) = a(x - p)(x - q), where a ≠ 0 and (p, 0) and (q...
A constant function p(x) = c, where c ≠ 0 is a polynomial function of degree 0 A linear function p(x) = mx + b, where m ≠ 0 is a polynomial function of degree 1 A quadratic function p(x) = ax2 + bx + c, where a ≠ 0 is a polynomial function of degree 2...
The roots of a quadratic equation are the two values of x, which are obtained by solving the quadratic equation. These roots of the quadratic equation are also called the zeros of the equation. For example, the roots of the equation x2 - 3x - 4 = 0 are x = -1 and x = 4 ...

What is a Quadratic Equation? For a quadratic function f(x)=ax2+bx+c, where a, b, and c are real numbers and a is nonzero, a quadratic equation outlines where the value of f(x) is equal to 0. The standard form of a quadratic equation is written as follows: ax2+bx+c=0;a≠...
