Question

determine between which consecutive integers the real zeros of each function are located.

f(x)=3x^3 – 10x^2 + 22x – 4 (I got 0,1)
f(x) = x^3 – 12x^2 + 17x – 9 (NO idea)
f(x) = x^3 – 9 (I got 8,9)

Thanks for the help, I really appreciate it. I need the most help with the second one, I couldn't even come up with an answer for that one.
