Explanation Given information: The functions are f ( x ) = x e k x and f ( x ) = x 2 e k x . Graph: For the graph of the function y = x e k x , substitute k = 0.1 in the function. To graph the above function, use the Ti-84 graphing calculator with the steps shown below: Step 1: Press the [ Y = ] key, and enter the right side of the function y = x e 0.1 x in Y 1 . Step 2: Press [WINDOW] key, and set the viewing window as below: X min = 0 X max = 50 Y min = − 1 Y max = 5 . Step 3: Press the [Graph] key to view the graph. The graph is obtained as follows: For the graph of the function y = x 2 e k x , substitute k = 0.1 in the function. To graph the above function, use the Ti-84 graphing calculator with the steps shown below: Step 1: Press the [ Y = ] key, and enter the right side of the function y = x 2 e 0.1 x in Y 1 . Step 2: Press [WINDOW] key, and set the viewing window as below: X min = 0 X max = 100 Y min = − 10 Y max = 60 . Step 3: Press the [Graph] key to view the graph. The graph is obtained as follows: For the graph of the function y = x e k x , substitute k = 0.5 in the function. To graph the above function, use the Ti-84 graphing calculator with the steps shown below: Step 1: Press the [ Y = ] key, and enter the right side of the function y = x e 0.5 x in Y 1 . Step 2: Press [WINDOW] key, and set the viewing window as below: X min = 0 X max = 10 Y min = − 0.1 Y max = 1 Step 3: Press the [Graph] key to view the graph
