The point of discontinuity of
Explanation of Solution
Given information:
The function is
Calculation:
Check the points of discontinuity of the function
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 function
Now check the continuity for
As observed from graph, the value of
As observed from graph, the value of
As the left hand limit of
So, the function
Therefore, the point of discontinuity of
(b)
To check:Whether the discontinuity of
(b)

Answer to Problem 21E
The discontinuity of
Explanation of Solution
Given information:
The function is
Calculation:
As calculated in part(a), the value of
So, the value of
Therefore, the discontinuity of
