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

x = 5 and x = 1

a. y = –x4 – 6x3 + 6x2 – 6x + 5
b. y = x4 + 6x3 – 6x2 + 6x – 5
c. y = x4 – 6x3 + 5x2 – 6x + 6
d. y = x4 – 6x3 + 6x2 – 6x + 5

Solve this (x-5)(x-1). Foil, and this will give you your answer.

But since you are give a list of answers, just solve them and see if they have those real zeros.

The last one on the list seems to have 1 and 5 as real zeros. Hope this helped.
