Understanding Zeros of Polynomial Functions

What is the significance of zeros in a polynomial function?

• They represent the maximum value of the function.

• They are the points where the function crosses the y-axis.

• They are the solutions or roots of the function.

• They indicate the slope of the function.

How does the degree of a polynomial function help in determining the number of zeros?

• It suggests the number of possible solutions or roots.

• It shows the highest power of the variable.
