Question

What is a quartic function with only the two real zeros given?

x = -4 and x = -1
A. y = x4 + 5x3 + 5x2 + 5x + 4
B. y = x4 - 5x3 - 5x2 - 5x - 4
C. y = -x4 + 5x3 + 5x2 + 5x + 4
D. y = x4 + 5x3 + 5x2 + 5x - 5

Answer 1

im thinking the answer is B

Answer 2

substitute x=-1 in each option and tell me those with y=0

Answer 3

Ummmmm *le stupid* Can you help walk me through one of the answers to find y=0 and i can do the same with the others...

Answer 4

"B. y = x4 - 5x3 - 5x2 - 5x - 4"
y = (-1)^4 - 5(-1)^3 - 5(-1)^2 - 5(-1) - 4
y = 1 + 5 - 5 + 5 - 4
y = 2
