Which of the following polynomials has degree 1?
Answer and explanation
Correct answer: \(9x-3\)
In the polynomial \(9x-3\), the highest power of the variable \(x\) is 1 and its coefficient is non-zero; therefore, its degree is 1. Polynomial A has degree 2, polynomial C has degree 3, and the constant polynomial \(11\) has degree 0. Exam tip: identify the highest power of the variable with a non-zero coefficient.
