What is the degree of the polynomial (9x-5)?
Answer and explanation
Correct answer: 1
In \(9x-5\), the variable term is \(9x=9x^1\). The highest exponent of \(x\) is \(1\), so the degree of the polynomial is \(1\). The constant term \(-5\) has degree \(0\), so it does not determine the degree. Exam tip: find the highest power of the variable to identify the degree of a polynomial.
