Question

11.
What is a quartic function with only the two real zeroes given?
x = –1 and x = –3 (1 point)

y = x4 –4x3 – 4x2 – 4x – 3
y = –x4 + 4x3 + 4x2 + 4x + 3
y = x4 +4x3 + 3x2 + 4x – 4
y = x4 + 4x3 +4x2 +4x +3

Answer 1

((x+1)*(x+3))^2 I think and expand

x^4+8*x^3+22*x^2+24*x+9

I dont think it is a choice tho but it is right.

Answer 2

thank you ( :

It not a choice :(

Answer 4

I'll figure it out( :

Answer 5

graph each one on google.

and the answer is the one which intersects the x axis
to copy to google for example instead of thish which you have
y = x4 –4x3 – 4x2 – 4x – 3

do this instead

x^4 –4*x^3 – 4*x^2 – 4*x – 3

* get rid of the "y=" ad the ^ for exponent and ad * between the coefficient and the x

Answer 6

Gotta go now

Answer 7

thank ya!!

Answer 8

\[y = x ^{4}+4x ^{3}+4x ^{2}+4x+3\] has -1 and -3 as its only real zeroes.
