How to determine function is a polynomial or not

The video tutorial explains how to classify polynomials by determining the leading coefficient and degree. It emphasizes the importance of following specific rules to ensure an equation qualifies as a polynomial. The tutorial highlights that having a variable in the denominator disqualifies an equation from being a polynomial, classifying it instead as a rational equation. This distinction is crucial for proper classification and understanding of polynomials.
