Which statement is correct for x^2/2 - 3x/4 + 9?

Answer and explanation

Correct answer: It is a polynomial and its degree is 2

A polynomial may have any real coefficients, including fractions, decimals, and irrational numbers. Rewrite the expression as (1/2)x^2 + (-3/4)x + 9. The powers of x are 2, 1, and 0, all of which are non-negative integers, and the coefficient of x^2 is 1/2, which is non-zero. Therefore the expression is a polynomial and its highest power is 2, so its degree is 2. Option A is false because fractional coefficients are allowed. Option C is false because the expression is not identically zero; for example, at x = 0 it equals 9. Option D is false because subtraction is equivalent to adding a negative term, which is permitted in a polynomial.
