what are the x intercepts : x^3 -9x^2 +27x -27
The question should be "what are the x-intercepts of y=x^3 -9x^2 +27x -27". Anyways, all you need to do is to solve: \[x^3 -9x^2 +27x -27=0.\] Hint: Use the factorization I helped you earlier with.
Oh you haven't done that problem yet. I'll help you there, in your earlier post.
