In (p(x)=7x^5-2x+4), the (x^4), (x^3), and (x^2) terms are missing. What is its degree?

Answer and explanation

Correct answer: 5

The degree of a polynomial is the greatest exponent of the variable among terms with non-zero coefficients. Here, the highest present term is 7x^5, so the degree is 5. The absence of x^4, x^3, and x^2 does not reduce the degree; 4 is only the next lower possible exponent, not the degree. Exam tip: To find the degree, look for the largest power of x with a non-zero coefficient.
