 Hello and welcome to the session. In this session we will discuss how to graph exponential functions using graphing calculator that is TI-83 plus calculator. Let us consider the function y is equal to 2 e raised to the power x. This is the TI-83 plus calculator and we want to graph y is equal to 2 e raised to the power x on it. First we begin with home screen and press y is equal to key. This takes us to the equation entering screen where we will write our equation. Now let us enter the equation 2 e raised to the power x into y1. For this first we press number 2 key then round bracket key. Now we see that e raised to the power x is written above ln key. So we press second key followed by e raised to the power x key and then we press xt theta n key for x and then we press this closing round bracket key twice. So we get the following display on the screen to view its graph we press graph key. On the screen the graph of the exponential function y is equal to 2 e raised to the power x will appear on the coordinate axis. To get a better view of this graph we can change the window settings to change window settings we press window key and we get the following display on the screen. Here we can see that we are given close interval from minus 10 to 10 by close interval from minus 10 to 10 window and we change it to close interval from minus 5 to 5 by close interval from minus 3 to 10 window for better display and we get this display on the screen. We know that to view its graph we have to press graph key. This is the required display of graph in new window. Now to know coordinate points on the graph we press trace key and we get the following display on the screen. Here we see that this point on the graph shows the value of x is 0 and the value of y is 2. To know other points on the graph we can scroll up and down the graph by pressing left and right arrow keys on the calculator. To have better view of coordinates lying on the graph we can see table of values for this we press second key followed by graph key we get the following table of values for this function. Thus we can graph exponential functions on TI 83 plus calculator. This completes our session. Hope you enjoyed this session.
