How to Find the Zeros of a Function with the TI-84 Silver Edition Plus

TL;DR

This video explains how to find the zeros of a function by graphing it on the TI-84 calculator.

Transcript

hi everyone in this video we're going to find the zeros of this function using the ti-84 calculator so in this example here all of the zeros of the function are real numbers so we're going to find it by graphing this function and finding the x-intercepts so to do that we're going to hit the y equals key right here and then I'm gonna hit clear and n...

Questions & Answers

Q: How can the TI-84 calculator be used to find the zeros of a function?

To find the zeros of a function, you can graph it on the TI-84 calculator and look for the x-intercepts or use the calc function for a more accurate result.

Q: What should be done if the graph on the calculator is not clear enough?

If the graph is not clear, you can use the zoom function on the TI-84 calculator to adjust the view, providing a better visual of the function.

Q: How can the calculator's "calc" function be used to find the zeros?

By accessing the calc function on the TI-84 calculator, you can input the left and right bounds of the zero and use the cursor to obtain accurate zero values.

Q: What is the significance of double-checking the input in the calculator?

Double-checking the input ensures that what is entered in the calculator matches the function being worked with, avoiding any mistakes in the calculations.
