Which option shows a polynomial of degree (4)?

Answer and explanation

Correct answer: \(x^4-3x+2\)

The degree of a polynomial in one variable is the greatest exponent of the variable. In \(x^4-3x+2\), the highest power of \(x\) is 4, so its degree is 4. Option B has degree 3 because \(x^3\) is its highest-power term. Exam tip: To find the degree, look for the greatest power of the variable; a constant term has degree 0.
