Quadratic function

• A quadratic function is 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 f ( x ) = x 2 + 4 x − 1 would be an example of a quadratic function because it has x to the second power as its highest term.
• Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations. The general form of the quadratic equation is: ax² + bx + c = 0.
• quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola.
• quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola.
• involving the square and no higher power of the unknown quantity; of the second degree.
• In general, if α is a root of the quadratic equation ax2 + bx + c = 0, a ≠ 0; then, aα2 + bα + c = 0. We can also say that x = α is a solution of the quadratic equation or α satisfies the equation, ax2 + bx + c = 0.
