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 a_n ≠ 0.

What does the leading term of a polynomial indicate?

Back

The leading term of a polynomial indicates the end behavior of the function as x approaches positive or negative infinity. It is determined by the coefficient and the degree of the polynomial.

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 determines the polynomial's end behavior and the number of zeros.

What are zeros of a polynomial?

Back

Zeros of a polynomial are the values of x for which the polynomial equals zero. They are also known as roots or x-intercepts.

How do you find the zeros of a polynomial?

Back

To find the zeros of a polynomial, set the polynomial equal to zero and solve for x. This can involve factoring, using the quadratic formula, or other algebraic methods.

What is the significance of the coefficient of the leading term?

Back

The coefficient of the leading term affects the direction of the polynomial's end behavior. A positive coefficient means the polynomial rises to the right, while a negative coefficient means it falls to the right.

What is end behavior in polynomial functions?

Back

End behavior describes how the values of a polynomial function behave as x approaches positive or negative infinity. It is influenced by the leading term's degree and coefficient.

What is the difference between even and odd degree polynomials?

Back

Even degree polynomials have symmetrical end behavior (both ends rise or fall), while odd degree polynomials have opposite end behavior (one end rises and the other falls).

What is a constant polynomial?

Back

A constant polynomial is a polynomial of degree 0, which means it has no variable term. Its graph is a horizontal line.

What is a linear polynomial?

Back

A linear polynomial is a polynomial of degree 1, which can be expressed in the form f(x) = ax + b, where a ≠ 0. Its graph is a straight line.
