Homework Help: TI-84 Plus Silver: Finding the Zeros

  1. Aug 6, 2011 #1
    1. The problem statement, all variables and given/known data
    I'm trying to learn how to use my TI-84 Plus Silver calculator and I want to know how to find the zeros of a function, but the calculator asks me to find the left and right bounds along with a guess. What is it asking me to do here?

    2. Relevant equations

    3. The attempt at a solution
    I've been messing around with the calculator by doing random inputs honestly. No luck.

    If I remember correctly, when looking at the graph, just pick an easy point that you can see that is to the left of the root. Again, pick a point on the graph that is to the right of the root. After that, it will hone in on the root and give you the answer.
