x^3 + 4x^2 + 14x + 20
use the root or zero feature of a graphing utility to approximate the zeros of the function accurate to three decimal places.
I do not know how to use the root or zero feature on my calculator. If someone could just explain how to do it that would be great.
I have a TI83 calculator
