Which option is a polynomial in (x) but appears to be written without (x) terms except a constant?

Answer and explanation

Correct answer: \(5\)

\(5\) is a constant polynomial in \(x\), because it can be written as \(5x^0\). The exponent of \(x\) is \(0\), which is a whole number. \(7y^2+3\) has \(y\) as its variable, so it is not treated as a polynomial in \(x\). In \(\frac{1}{x}\), the exponent of \(x\) is \(-1\), and in \(\sqrt{x}\), it is \(\frac{1}{2}\); therefore, neither is a polynomial in \(x\). Exam tip: exponents of the variable in a polynomial can only be \(0,1,2,\ldots\).
