a.
To graph: f and g in the same viewing window using a graphing utility.
a.
Explanation of Solution
Given information: Consider the function
Graph:
The graph of f and g in the same viewing window using a graphing utility is shown below.
b.
To find: The interval in which
b.
Answer to Problem 72E
The interval for which
Explanation of Solution
Given information: Consider the function
Calculation:
From the graph, it looks like they intersect when both=1 .This will happen when For the given interval, this is when
So, the interval for which
c.
To Describe: The behavior of each of the function as x approachesTo find how is the behavior of g related to the behavior of f as x approaches
c.
Answer to Problem 72E
The g goes to as x approaches
Explanation of Solution
Given information: Consider the function
Calculation:
Note that the two functions are reciprocals of each other.
As from the left, just goes to 0, so f goes to 0.
and dividing by a tiny number results in a very large number, so g goes
