A parabola is the graph of a quadratic polynomial. The places where the parabola cuts the x-axis, i.e. The points in a quadratic equation at which the value of the quadratic polynomial equals 0 are known as the roots of the equation.
The term “quadratic function” refers to a polynomial function that is of the second degree.
As an illustration of the general form of a quadratic function, consider the following example: The expression for f (x) can be written as ax² + bx + c, where a, b, and c are all numbers that can exist in the real world.
