The best answer is A. The possible roots of this polynomial function 9i and -9i. It is possible that this polynomial function is a quadratic equation. It has a degree of two which means there are two roots and it is possible that the positive and negative value of 9i are its roots.

Y/2 - (-1.12) = 3.12
ahrayia [7]

\fbox{y=4}

\frac{y}{2} -(-1.12)=3.12

Simplify:

\frac{1}{2} y+1.12=3.12

Subtract 1.12 on both sides:

\frac{1}{2} y+1.12-1.12=3.12-1.12

\frac{1}{2} y=12

Multiply both sides by 2:

2\times(\frac{1}{2} y)(2)\times(2)

y=4
