Define a polynomial function.

Back

A function that is represented by a polynomial expression, which is a sum of terms consisting of a variable raised to a non-negative integer power.

Back

The highest power of the variable in the polynomial.

Front

What is the significance of the leading coefficient in a polynomial function?

Back

It determines the end behavior of the graph of the polynomial.

Front

What does it mean for a polynomial to have a multiplicity greater than 1?
