Which polynomial is a constant polynomial?
Answer and explanation
Correct answer: \(-7\)
A constant polynomial does not contain a variable, so its value remains fixed. Since \(-7\) contains no variable \(x\), it is a constant polynomial. The other options contain \(x\), so they are non-constant polynomials. In an exam, first check whether the variable appears in the expression.
