(a)
Explanation of Solution
Given information:
A continuous function that is
Graph:
The sigma function is defined as the function which has the value -1for the negative argument, 0 when the argument is 0 and 1 for the positive argument.
The graph for the given continuous function
Interpretation:
From the graph it is obtained that the value -1 has negative argument and 1 has positive argument. The graph is increasing and decreasing with respect to the argument value

Answer to Problem 28E
The input should be within -0.001 to 0.001 for the output to be within 0.1 to 0.
Explanation of Solution
Given information:
A continuous function that is
Calculation:
The given function is
To determine the input at
Similarly, consider
From the two values of
Hence, the input should be within -0.001 to 0.001 for the output to be within 0.1 to 0.
