First press “ON” button on graphical calculator and press
Press Enter. To write the function
Again press Enter. To write the function
The display will show the equations,
Now, press the
Figure (1)
Interpretation: The graph of the piecewise function shows is a horizontal line except the interval
(b)

(b)

Answer to Problem 64E
The limit
Explanation of Solution
Given information: The function is
Calculation:
The function
The function exist for all points less than
Therefore, the limit
(c)
To find: The points
(c)

Answer to Problem 64E
There is no point
Explanation of Solution
Given information: The function is
Calculation:
As observed from the graph in part (a), the function is defined for every point in the domain of the function. So, left hand limit exist at every point.
Therefore, there is no point
(d)
To find: The points
(d)

Answer to Problem 64E
There is no point
Explanation of Solution
Given information: The function is
Calculation:
As observed from the graph in part (a), the function is defined for every point in the domain of the function. So, right hand limit exist at every point.
Therefore, there is no point
