2-69.

Suppose you wish to find outputs for the function y = x3 on the interval 1 ≤ x ≤ 3, by tenths. Your calculator can do this easily with the [TABLE] command. First use [TBLSET] ([2nd] [WINDOW]) to set up the table. Make TblStart = 1, ΔTable = 0.1. Highlight Auto for both the independent and dependent variables. The function y = x3 should be entered in Y1. The values for x appear with their corresponding y-values (e.g. when x = 1.5, y = 3.375). You can scroll up and down the list with the arrow buttons to find the output(s) you want. What is the value of y when x = 2.7? Homework Help ✎

y = 2.73 = 19.683
