Q. Select the correct answer.(\newline\)What is the degree of the polynomial function (\newline\)f(x)=2x3+7x24x12f(x)=2x^{3}+7x^{2}-4x-12,(\newline\)A. 33(\newline\)B. 55(\newline\)C. 22(\newline\)D. 1313
  1. Definition of Degree: The degree of a polynomial is the highest power of the variable xx that appears in the polynomial with a non-zero coefficient.
  2. Combine Like Terms: First, we combine like terms in the polynomial f(x)=2x3+7x34x12f(x) = 2x^3 + 7x^3 - 4x - 12. The like terms here are the terms with x3x^3.
  3. Simplify Polynomial: Combining the like terms gives us f(x)=(2x3+7x3)4x12f(x) = (2x^3 + 7x^3) - 4x - 12, which simplifies to f(x)=9x34x12f(x) = 9x^3 - 4x - 12.
  4. Identify Highest Power: Now that we have simplified the polynomial, we can see that the highest power of xx is 33 in the term 9x39x^3.
  5. Degree of Polynomial: Therefore, the degree of the polynomial f(x)=9x34x12f(x) = 9x^3 - 4x - 12 is 33.
