Is 2x^2 + 3|x| + 1 a polynomial or not?

Answer and explanation

Correct answer: No, because |x| is not a polynomial term

Under the standard algebraic definition, a polynomial in x is a finite sum of terms of the form ax^n, where n is a non-negative integer. The terms 2x^2 and 1 satisfy this condition, but |x| does not have that form. Absolute value is defined piecewise: |x| = x for x greater than or equal to 0 and |x| = -x for x less than 0. Consequently, the whole expression has different formulas on different intervals and is not one polynomial in x. The number of terms, the presence of a constant, or the presence of x^2 cannot by itself make an expression a polynomial. Therefore option B identifies the precise reason and is correct.
