Absolute polynomial question (driving me nuts)

In summary, an absolute polynomial is a mathematical expression that only contains non-negative integer exponents. It differs from other polynomials by not having any negative exponents or variables with fractional powers, making it always positive or zero for all values of the variable. To simplify an absolute polynomial, you can combine like terms and use the distributive property. Applications of absolute polynomials include modeling real-world situations, solving optimization problems, and finding maximum or minimum values. To solve an absolute polynomial equation, you can use algebraic or numerical methods.

|x^2 - 2x - 3| = -(x^2 - 2x - 3), 0 <= x < 3
x^2 - 2x - 3, 3 <= x <=4

how did they get the intervals:
3 <= x <=4 and 0 <= x < 3?

I cannot, for the love of God, know how they determined it. :mad:

Remember the definition of absolute value:

[tex]
|q| := \left\{ \begin{array}{ll} q \quad & q \geq 0 \\ -q \quad & q \leq 0 \end{array}
[/tex]


Anyways, it sounds like there's also more to the problem than you gave us.

What is an absolute polynomial?

An absolute polynomial is a mathematical expression that contains only non-negative integer exponents. It can be written in the form of ax^n + bx^(n-1) + ... + cx + d, where a, b, c, and d are constants and n is a positive integer.

What makes absolute polynomials different from other polynomials?

Unlike other polynomials, absolute polynomials do not have any negative exponents or variables with fractional powers. This means that they are always positive or zero for all values of the variable.

How do you simplify an absolute polynomial?

To simplify an absolute polynomial, you can combine like terms by adding or subtracting the coefficients of terms with the same variable raised to the same power. You can also use the distributive property to factor out common terms.

What are the applications of absolute polynomials?

Absolute polynomials are commonly used in fields such as mathematics, physics, and engineering to model real-world situations and make predictions. They are also useful for solving optimization problems and finding the maximum or minimum values of a function.

How do you solve an absolute polynomial equation?

To solve an absolute polynomial equation, you can use algebraic methods such as factoring, the quadratic formula, or completing the square. You can also use numerical methods such as graphing or using a calculator to find approximate solutions.
