Check the limit graphically.
To graph a function
First press “ON” button on graphical calculator, press
The display will show the equation,
Now, press the
Figure (1)
As observed from the graph, the value of function tends to
So, the right hand limit and left hand limit both tends to
Therefore, the curve
