Question

Which second degree polynomial function has a leading coefficient of –1 and root 4 with multiplicity 2?

f(x) = –x2 – 8x – 16

f(x) = –x2 + 8x – 16

f(x) = –x2 – 8x + 16

f(x) = –x2 + 8x + 16

Answer 1

The answer is B. Just took the test.

Explanation:

Answer 2

Hello,

f(x)=-(x-4)²=-(x²-8x+16)=-x²+8x-16

Answer B
