(a)
Explanation of Solution
Given information: The piecewise function
Graph:
To graph a function
First press “ON” button on graphical calculator, press
Now, enter the key
The display will show the equation,
Adjust the window at
Now, press the
Figure (1)
Interpretation: The graph of the piecewise function
(b)
To find: The value of limits
(b)
Answer to Problem 59E
The value of limit
Explanation of Solution
Given information: The piecewise function is
Calculation:
As for the right side of the point
Use the function
Substitute
So, the value of
Now for the left side of the point
Use the function
This does not exist as it forms
So, the value of
Therefore, the value of limit
(c)
To check: Whether the limits
(c)
Answer to Problem 59E
The limit
Explanation of Solution
Given information: The piecewise function is
As calculated in part (b), the value of limit
Therefore, the limit
