What is the degree of the polynomial (3x^4-5x^2+7x-1)?

Answer and explanation

Correct answer: 4

The degree of a polynomial is the highest exponent of its variable with a non-zero coefficient. The exponents of the terms in the given polynomial are 4, 2, 1, and 0. The greatest exponent is 4, so its degree is 4. Option 2 is only the exponent of the term -5x^2, not of the whole polynomial. Exam tip: A constant term has degree 0.
