Which polynomial has degree (3)?
Answer and explanation
Correct answer: \(2x^3+6\)
The degree of a polynomial is the highest power of its variable with a non-zero coefficient. In \(2x^3+6\), the highest power of \(x\) is \(3\), so its degree is \(3\). \(4x^2+1\) is the closest distractor, but its degree is \(2\). Exam tip: A non-zero constant polynomial has degree \(0\).
