A cubic equation is one of the **form ax ^{3} + bx^{2} + cx + d = 0 where a,b,c and d are real numbers**. For example, x

A cubic equation is an equation which can be represented in the form **a x 3 + b x 2 + c x + d = 0 ax^3+bx^2+cx+d=0 ax3+bx2+cx+d=0**, where a , b , c , d a,b,c,d a,b,c,d are complex numbers and a is non-zero. By the fundamental theorem of algebra, cubic equation always has 3 roots, some of which might be equal.

A cubic equation is an algebraic equation of third-degree.

The general form of a cubic function is: **f (x) = ax ^{3} + bx^{2} + cx^{1} + d**. And the cubic equation has the form of ax

The general strategy for solving a cubic equation is **to reduce it to a quadratic equation, and then solve the quadratic by the usual means**, either by factorising or using the formula. are all cubic equations. Just as a quadratic equation may have two real roots, so a cubic equation has possibly three.

A Cubic Model uses a cubic functions (of the form begin{align*}ax^3+bx^2+cx+dend{align*}) to model real-world situations. They can be used to **model three-dimensional objects to allow you to identify a missing dimension or explore the result of changes to one or more dimensions**.

Gerolamo Cardano

Gerolamo Cardano is credited with publishing the first formula for solving cubic equations, attributing it to Scipione del Ferro.

Degree 3 – cubic. Degree 4 – **quartic** (or, if all terms have even degree, biquadratic) Degree 5 – quintic. Degree 6 – sextic (or, less commonly, hexic)

A **polynomial having its highest degree 3** is known as a Cubic polynomial. For example, f (x) = 8×3 + 2×2 – 3x + 15, g(y) = y3 – 4y + 11 are cubic polynomials.

- First set the coefficients in different cells.
- Set the initial value of X as “0” in cell B6.
- After that write the polynomial equation in cell G3 with respect to the cells of coefficients and the initial value of X.

Lesson Summary. A cubic function is **any function of the form y = ax3 + bx2 + cx + d**, where a, b, c, and d are constants, and a is not equal to zero, or a polynomial functions with the highest exponent equal to 3.

discriminant, in mathematics, a parameter of an object or system calculated as an aid to its classification or solution. In the case of a quadratic equation ax^{2} + bx + c = 0, the discriminant is b^{2} − 4ac; for a cubic equation x^{3} + ax^{2} + bx + c = 0, the discriminant is a** ^{2}b^{2} + 18abc − 4b^{3} − 4a^{3}c − 27c^{2}**.

The “basic” cubic function is **f(x) = x ^{3}**. You can see it in the graph below. In a cubic function, the highest power over the x variable(s) is 3. The coefficient “a” functions to make the graph “wider” or “skinnier”, or to reflect it (if negative): The constant “d” in the equation is the y-intercept of the graph.

If y = f(x + d) and d > 0, the graph undergoes a horizontal shift d units to the left. **If y = f(x + d) and d , the graph undergoes a horizontal shift d units to the right.**

Polynomial Functions.

Degree of the polynomial | Name of the function |
---|---|

Constant function | |

1 | Linear function |

2 | Quadratic function |

3 | Cubic function |

Hence, **3/2** is the zero of the polynomial 2x – 3.

Cubic sequences are characterized **by the fact that the third difference between its terms is constant**. For example, consider the sequence: 4,14,40,88,164,… … Looking at this we can see that the third difference is constant, and not equal to zero, this means it is a cubic sequence.

We will use the sum, sum of the products and products given in the question to find the cubic polynomial. **sum of products = α+β+γ=−ba**, where b is the coefficient of x2 and a is the coefficient of x3. Also, we have a sum of products taken two at a time = αβ+βγ+γα=ca, where c is the coefficient of x.

A cubic polynomial is **a polynomial of degree 3**. A univariate cubic polynomial has the form. . An equation involving a cubic polynomial is called a cubic equation. A closed-form solution known as the cubic formula exists for the solutions of an arbitrary cubic equation.

Cubic Trinomials of the Form Ax^3 + Bx+^2 + Cx

For example, the greatest common factor of the trinomial 3x^3 – 6x^2 – 9x is 3x, so the polynomial is equal to 3x times the trinomial x^2 – 2x -3, or 3x*(x^2 – 2x – 3). … For example, the polynomial x^2 – 2x – 3 factors as (x – 3)(x + 1).

A cubic trinomial is **a trinomial in one variable with a degree of 3**.

To calculate the cube root of a number in Excel, **use the caret operator (^) with 1/3 as the exponent in a** simple formula. In this example, the formula =D3^(1/3) is used to find the cube root of 216, which is 6.

Graphing cubic functions **gives a two-dimensional model of functions where x is raised to the third power**. Graphing cubic functions is similar to graphing quadratic functions in some ways. In particular, we can use the basic shape of a cubic graph to help us create models of more complicated cubic functions.
## Are cubic functions even or odd?

## What are the roots of cubic equation?

## What is discriminant used for?

This cubic is centered at the point (0, –3). This graph is symmetric, but not about the origin or the y-axis. So this **function is neither even nor odd**. … Since it is mirrored around the y-axis, the function is even.

The three roots of x3 + ax + b are **the real numbers 2R, -R + /3I, and -R – /3I**. These four steps together are the cubic formula. It uses complex numbers (D and z) to create real numbers (2R, -R + /3I, and -R – /3I) that are roots of the cubic polynomial x3 + ax + b.

The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells **us whether there are two solutions, one solution, or no solutions**.
