Instructions

1.Enter the exponential function into the Input Bar and press Enter.
Hint: Use the Virtual Keyboard to type in the exponent.
2.Zoom out of the Graphics View, so you can see the graph of the function.
3.Open the context menu by pressing the More button on the right side of the row containing f(x).
4.Select Table of values. A dialog opens where you can define Start value for x, End value for x and Step. Set the start value to 0, the end value to 10 and the step to 1. Press OK to confirm your settings.
5.The Table View opens automatically so you can see the values immediately.
6.Go back to Algebra View, type into the Input Bar and press Enter.
7.Open the context menu by pressing the More button on the right side of the row containing g(x). Select Table of values again.
Note: This time the dialog for defining start and end values will not show, because you already set those values in step 4. You can change the values later.
8.The Table View opens automatically so you can see the values immediately and compare the two functions.
