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

1) Enter the equation by pressing the "Y=" button on the left side and entering in "x^3 + 4x^2 + 14x + 20"
2) Press "GRAPH" on the right side
3) Press "2nd" "Calc/Trace" "2. Zero" 
im sorry but what was the answer i don't have a ti83 i have a cassio would u by any chance no how to do this
