Which option has polynomial degree (5)?
Answer and explanation
Correct answer: \(4x^5-3x^2+1\)
The degree of a polynomial is the highest exponent of the variable with a non-zero coefficient. In \(4x^5-3x^2+1\), the highest power of \(x\) is \(5\), so its degree is \(5\). Option B has highest power \(4\), so it is not correct. Exam tip: To find the degree, look for the greatest exponent of the variable, not the constant term.
