How many unique roots will a fifth degree polynomial function have ?

5

Step-by-step explanation:

The polynomial of the form will have a maximum of one root or zeros because the highest degree of the variable is one.

The polynomial of the form will have a maximum of two root or zeros because the highest degree of the variable is two.

similarly

The polynomial of the form will have a maximum of five root or zeros because the highest degree of the variable is five.
