if anyone helps i will give a METAL!!!

1)Determine which consecutive integers do not have a real zero of f(x) = x3 – 9x2 + 23x – 14.

2)For f(x) = x3 – 3x2, determine the number and type of possible complex zeros, and find the zeros to the nearest tenth.

For questions 3–5, determine between which consecutive integers the real zeros of each function are located.
3) f(x) = 3x^3 – 10x^2 + 22x – 4
4) f(x) = x^3 – 12x^2 + 17x – 9
5) f(x) = x^3 – 9
I really need help with this thank you to anyone for anyone who can help.
