At least I have a substitute teacher during quarantine. Very helpful, thanks.

Great video! I'm really confused on how you picked 2 as the value of x0? do you just pick a random number, because in the exam you would be finding the roots so wouldn't know an interval to pick between?

I'd like to know how you sketched the curve of the iteration formula in order to find how many intersections it had with the line y=x?

would it be possible to rearrange the initial equation to x=cube root(15x-15), to find the other roots?

So are you using staircase methods to help you in this method?

why is it that when i rearranged the equation like x=cube root(15x-5), I get a different value of 3.69?
