What is the sum of the coefficients of the odd-power terms in the polynomial p(x) = 5x^5 - 3x^4 + 2x^3 - x + 6?

Answer and explanation

Correct answer: 6

The odd-power terms are 5x^5, 2x^3, and -x. Their coefficients are 5, 2, and -1, so their sum is 5 + 2 - 1 = 6. Option 7 results from mishandling the negative coefficient of -x. In an exam, remember that the term x has power 1, which is also odd.
