Which polynomial is a cubic polynomial?

Answer and explanation

Correct answer: \(4x^3-6x+1\)

A polynomial whose highest power of the variable is 3 is called a cubic polynomial. In \(4x^3-6x+1\), the highest power of \(x\) is 3, so it is cubic. \(x^2+8\) is quadratic because its degree is 2. Exam tip: To find the degree of a polynomial, identify the greatest exponent of the variable.
