I think I may just be confused on the "zero Routine" wording, but this problem reads "The height of the ball is given by the function -16t^2-32t+229 solve using the Zero routine on your TI-83 calculator." What exactly is the Zero Routine? Thanks!!!! and How would I apply it to this function. Thanks!!
Hello,
1. write the term of the function at Y1=
2. graph the function by pressing the GRAPH-button
3. normally you will not see very much so press ZOOM-button and choose 0:ZoomFit
4. press 2ND+TRACE (it's the command CALC)
5. choose for 2:zero
6. you will be prompted to give in a left and a right bound which you can do with the cursor. Be sure that the cursor crosses the x-axis
7. type in a guess (with your problem -5 will do fine)
8. you'll get the nearest zero

PS: I used a TI84 but I believe (and hope) the syntax is similar to a TI83
