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 TI-83 calculator

  • math -

    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"
