Concept
In \(5+x^3-2x\), the powers are (0), (3), and (1), but all are valid. Writing in descending order is not required.
Why this answer is correct
The correct answer is A. \(5+x^3-2x\). In \(5+x^3-2x\), the powers are (0), (3), and (1), but all are valid. Writing in descending order is not required.
