In p(t) = 2t⁴ − 7t² + 3, which term determines the degree?

Answer and explanation

Correct answer: 2t⁴

The governing concept is the degree of a polynomial. The degree is the greatest exponent of the variable among all non-zero terms. In p(t) = 2t⁴ − 7t² + 3, the powers of t are 4, 2, and 0, corresponding to 2t⁴, −7t², and 3. The term 2t⁴ has the greatest exponent, so it determines the polynomial’s degree, which is 4. Therefore option C is correct. The constant 3 has degree 0, while 7t² has degree 2, so neither determines the overall degree. Option D lists two terms together rather than identifying the single highest-power term requested by the question.
