$\"\"$

The function is $\"\"$ .

The general form of polynomial function is $\"\"$ ,

where $\"\"$ are real numbers and $\"\"$ is a non-negative integer.

The power of variable $\"\"$ is a non-negative integer, hence it is a polynomial function.

The degree of the polynomial function is the largest power of $\"\"$ and appears to be degree $\"\"$ . \ \

$\"\"$

The function $\"\"$ is a polynomial function and the degree of $\"\"$ is $\"\"$ .
