Homework Statement

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?

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.

Thank you. I see what I did wrong, haha.
