Because they have an odd degree, normal quintic functions appear similar to normal cubic functions when graphed, except they may possess one additional local maximum and one additional local minimum. The derivative of a quintic function is a quartic function. Setting g(x) = 0 and assuming a ≠ 0 produces a quintic equation of the form:
Algebraic functions are functions that can be expressed as the solution of a polynomial equation with integer coefficients. Polynomials: Can be generated solely by addition, multiplication, and raising to the power of a positive integer. Constant function: polynomial of degree zero, graph is a horizontal straight line
In mathematics, a quartic equation is one which can be expressed as a quartic function equaling zero. The general form of a quartic equation is The general form of a quartic equation is Graph of a polynomial function of degree 4, with its 4 roots and 3 critical points .
Graph of a polynomial of ... seven. If a = 0, then f is a sextic function (b ≠ 0), quintic function ... The equation may be obtained from the function by setting f ...
is called a biquadratic function; equating it to zero defines a biquadratic equation, which is easy to solve as follows Let the auxiliary variable z = x 2. Then Q(x) becomes a quadratic q in z: q(z) = a 4 z 2 + a 2 z + a 0. Let z + and z − be the roots of q(z). Then the roots of the quartic Q(x) are
The polynomial () (+) is a cubic polynomial: after multiplying out and collecting terms of the same degree, it becomes + +, with highest exponent 3.. The polynomial (+ +) + (+ + +) is a quintic polynomial: upon combining like terms, the two terms of degree 8 cancel, leaving + + + +, with highest exponent 5.
A sextic function is a function defined by a sextic polynomial. Because they have an even degree, sextic functions appear similar to quartic functions when graphed, except they may possess an additional local maximum and local minimum each. The derivative of a sextic function is a quintic function.
The quintic Hermite interpolation based on the function (), its first (′) and second derivatives (″) at two different points (and ) can be used for example to interpolate the position of an object based on its position, velocity and acceleration.
