Reema claims that \(7-3x+\frac{2}{x}\) is a linear polynomial because the highest power of \(x\) in it is 1. Which is the correct correction to her claim?

Answer and explanation

Correct answer: It is not a polynomial because \(\frac{2}{x}=2x^{-1}\) has a negative exponent of \(x\).

Writing \(\frac{2}{x}=2x^{-1}\) gives an exponent of \(-1\). In a polynomial, variable exponents must be 0, 1, 2, …, so this is not linear. Exam tip: check for variables in denominators first.
