Which statement is correct for (x^0+x^{-2}+3)?

Answer and explanation

Correct answer: It is not a polynomial because it contains x^{-2}

Option B is correct. Here, x^0=1, so a zero exponent is perfectly valid. However, x^{-2}=\(\frac{1}{x^2}\), which gives the variable a negative exponent. In a polynomial, variable exponents must be 0 or positive integers; therefore, the given expression is not a polynomial. Option A considers only x^0 and ignores x^{-2}. Exam tip: To identify a polynomial, first check whether any variable has a negative or fractional exponent.
