Which expression is not a polynomial in x because it contains log x?

Answer and explanation

Correct answer: x² + log x

A polynomial in x is a finite sum of terms of the form axⁿ, where a is a constant and n is a non-negative integer. The term log x is logarithmic, not a power of x with an allowed integer exponent. Consequently, option A is not a polynomial in x. Option B uses powers 2, 1 and 0, so it is a polynomial. In option C, √2 is merely a constant coefficient and can be viewed as √2x⁰; its presence does not cause a problem. Option D uses powers 0 and 1. Thus irrational constants and addition are allowed, but logarithmic dependence on x is not. Therefore option A is the unique correct answer.
