What is a cubic function?

Back

A cubic function is a polynomial function of degree three, which can be expressed in the form f(x) = ax^3 + bx^2 + cx + d, where a ≠ 0.

What does it mean for a polynomial to have multiple zeros?

Back

A polynomial has multiple zeros when a particular zero occurs more than once, indicating that the graph touches or crosses the x-axis at that point.

What is the significance of the x-intercepts in a polynomial graph?

Back

The x-intercepts (or zeros) indicate the values of x for which the polynomial function equals zero, showing where the function changes sign.

How do you classify a polynomial based on its degree?

Back

Polynomials are classified as linear (degree 1), quadratic (degree 2), cubic (degree 3), quartic (degree 4), and so on.

What is the relationship between the degree of a polynomial and the number of zeros it can have?

Back

A polynomial of degree n can have up to n real zeros, counting multiplicities.

Front

What is a root of a polynomial?

Back

A root of a polynomial is a solution to the equation formed by setting the polynomial equal to zero.

How can you verify the zeros of a polynomial?

Back

You can verify the zeros of a polynomial by substituting the zero back into the polynomial equation and checking if it equals zero.

Front

What is the difference between a zero and a root?

Back

There is no difference; the terms 'zero' and 'root' are often used interchangeably in the context of polynomials.
