A student says that the degree of \(6y^3-y+9\) is 1 because the exponent of \(y\) is 1. Which statement correctly fixes the student's error?

Answer and explanation

Correct answer: The degree is 3 because the greatest exponent of \(y\) among terms with non-zero coefficients is 3.

The degree of a polynomial is the greatest exponent of the variable among terms with non-zero coefficients. In \(6y^3-y+9\), the exponents of \(y\) are 3, 1, and 0 respectively, so the greatest exponent is 3. Looking only at the term \(-y\) and choosing 1 is incorrect. Exam tip: identify the exponent in every term before selecting the greatest one.
