To find: The domain of the provided function.
Answer to Problem 8RE
Solution:
The domain of the function is .
Explanation of Solution
Given:
It is provided in the problem that the function is .
Formula used:
Rules used to find the domain of a function defined by an equation:
1. Start with the domain as the set of all numbers.
2. If the equation has a denominator, exclude any numbers that give a zero denominator.
3. If the equation has a radical of even index, exclude any numbers that cause the expression inside the radical (the radicand) to be negative.
The function says to divide by . Since division by 0 is not defined, the denominator can never be 0, so can never equal 0. The domain of the function is .
