at 11:12 you say that ⎷-9 equals 3i or -3i.. But that means that ⎷4 equals 2 or -2. And that not what you do in the table. So an error again in what you tell us. Why do you make so many mistakes in what you try to tell us? ⎷-9 equals 3i or -3i is a false statement!
I love that your my teacher
But be careful, he makes many errors in his videos. See for instance my comment on what he says about ⎷-9
would have been nice if he explained why the graph isn't a sideways parabola. For instance: when f(x)= squareroot(x) and x=4, f(x) and equal 2 or -2
