What is the leading coefficient of the polynomial \(p(y)=9y^4-y^2+5y-6\)?

Answer and explanation

Correct answer: 9

The term with the highest power in the polynomial is \(9y^4\). Its coefficient is 9, so the leading coefficient is 9. The value -1 in option B is the coefficient of the \(y^2\) term, not the leading term. Exam tip: identify the highest-degree term first, then take its coefficient.
