Which expression is a polynomial in (x), if (a) and (b) are constants?
Explanation opens after your attempt
A. \(ax^3+b x+9\)
Concept
(a) and (b) act like coefficients. The powers of (x) are (3), (1), and (0), which are valid.
Why this answer is correct
The correct answer is A. \(ax^3+b x+9\). (a) and (b) act like coefficients. The powers of (x) are (3), (1), and (0), which are valid.
