We are given roots of a polynomial function : i, –2, and 2.
And leading coefficient 1 .
We need to find the polynomial function of lowest degree.
<em>Please note: We have one root i, that is a radical root. And a radical always comes in pair of plug and minus sign.</em>
Therefore, there would be another root -i.
So, we got all roots of the polynomial function : i, -i, -2, and 2.
For the given roots, we would have factors of the polynomial (x-i)(x+i)(x+2)(x-2).
Now, we need to multiply those factors to get the polynomial function.
