2) f(x) = 2x^7 + 2x^6 + 7x^5 + 7x^4 - 4x^3 + 4x^2 f(-x) = -2x^7 + 2x^5 - 7x^5 + 7x^4 + 4x^3 + 4x^2 There are 3 changes of sign in f(-x), which means there can be possibly either 3 negative zeros or just 1 negative zero. So the answer would be B.

\[f(-x)=-2(-x)^7+2(-x)^6+7(-x)^5+7(-x)^4+4(-x)^3+4(-x)^2\]
