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

    ((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.

    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

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