Exponential Regressions with TI-83, TI-83- Plus and TI-84

Many of us go out to the store and buy a graphing calculator, then when we get home, we wonder what next? The purpose of these tutorials is the answer that question!
1) Click on the STAT button of your TI 84
2) Select "Edit".
    Here you will see vertical columns with l1 (list 1), L2(list 2) etc.. These columns are where you type in your ordered paris, your x and y values. X values goes in l1 and y values go into l2.

3) Enter your x and y values into the Screen (This example will use the ordered the values in the picture on the right)
4 )Press "STAT" And scroll right once to highlight “CALC”
5) Scroll down to item ‘0’ which says ExpReg
5) Hit enter twice (first time just gets ExpReg on screen; on second, the TI actually calculates the exponential regression) to see the exponential regression. If you used the numbers on the page up, above you should see the following screen.
6) Therefore, the exponential equation that best fits this data is y = 1.923930724 (3.053280546)x
