What is a polynomial function?

Back

A polynomial function is a mathematical expression involving a sum of powers in one or more variables multiplied by coefficients. The general form is f(x) = a_n*x^n + a_(n-1)*x^(n-1) + ... + a_1*x + a_0, where n is a non-negative integer.

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the polynomial expression. It indicates the polynomial's behavior and the number of roots it can have.

What is the leading coefficient of a polynomial?

Back

The leading coefficient is the coefficient of the term with the highest degree in a polynomial. It influences the end behavior of the polynomial function.

How do you determine the degree of the polynomial f(x) = 2x^3 - 3x^2 + 4x - 10?

Back

The degree of f(x) = 2x^3 - 3x^2 + 4x - 10 is 3, as the highest power of x is 3.

How do you determine the degree of the polynomial f(x) = -3x^4 + x^3 - 2x^2 + x - 1?

Back

The degree of f(x) = -3x^4 + x^3 - 2x^2 + x - 1 is 4, as the highest power of x is 4.

What is the standard form of a polynomial?

Back

The standard form of a polynomial is written in descending order of the degree of its terms, starting from the highest degree to the lowest.

What is a monomial?

Back

A monomial is a polynomial with only one term, such as 5x^2 or -3.

Front

What is a binomial?

Back

A binomial is a polynomial with exactly two terms, such as x + 2 or 3x^2 - 4.

Front

What is a trinomial?

Back

A trinomial is a polynomial with exactly three terms, such as x^2 + 5x + 6.

What is the difference between a polynomial and a non-polynomial function?

Back

A polynomial function consists of terms with non-negative integer exponents, while non-polynomial functions may include negative exponents, fractions, or variables in the denominator.
