How do you write a polynomial function given the real zeroes 8,-i, i and coefficient 1?
For each zero c, meaning f(c) = 0, your function f(x) has to have a factor (x - c). Your function needs ___ factors. (You fill in!)
We have zeroes:
So we will have factors:
Does this have the right (leading) coefficient?
You'll learn more if you finish this yourself!
(shortcut: use difference of squares!)
