Figure (1)
Interpretation: The graph of the piecewise function
(b)
To find: The value of limits
(b)
Answer to Problem 57E
The value of limits
Explanation of Solution
Given information: The piecewise function
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
Substitute
So, the value of
Therefore, the value of limits
(c)
To check: Whether the limit
(c)
Answer to Problem 57E
The limit
Explanation of Solution
Given information: The piecewise function
As calculated in part (b), the value of limits
The left hand limit for
Therefore, the limit
