Front

Define a polynomial function.

Back

A polynomial function is a mathematical expression involving a sum of powers in one or more variables multiplied by coefficients.

Front

What is the leading coefficient of the polynomial f(x) = -7x^3 + 2x - 1?

Back

-7.

Front

How do you determine the degree of a polynomial?

Back

The degree of a polynomial is determined by the highest power of the variable in the polynomial.

Front

What does it mean for a polynomial to have a degree of 3?

Back

It means the polynomial is cubic and can have up to 3 real roots.

Front

What is the significance of the constant term in a polynomial?

Back

The constant term is the value of the polynomial when the variable is zero.
