Answer to Problem 108E
The domain of our given logarithmic function would be
Explanation of Solution
Given:
A function:
Calculation:
We know that logarithmic functions are not defined for negative values.To find domain of our given function, we will set argument of logarithmic function greater than0 as:
Therefore, the domain of our given logarithmic function would be or
