Answer to Problem 47RE
The domain is
The range of the function is
Explanation of Solution
Given information: The secant function.
Calculation: The secant function,
For, The real number output
Therefore, The domain of the function is all real numbers except the values where
Hence, The domain is
The range of the function is
If a function has a repeating pattern, it’s called periodic function. The period is the length of the smallest interval that contains exactly one copy of the repeating pattern.
