Question
What is the domain of the logarithmic function 𝑦=?
Give your answer using interval notation; e.g. oc(2,3) for (2,3].
Solution
Break Down the Problem
- Identify the properties of the logarithmic function.
- Determine the values of for which is defined.
Relevant Concepts
- The logarithmic function is defined for .
- The domain of a function is the set of all possible input values (x-values) that does not lead to undefined results (like negative values or zero in the case of logarithms).
Analysis and Detail
- Since is only defined for positive values of , we can express this restriction mathematically:
- This means that can take any value greater than zero, but not equal to zero or any negative value.
Verify and Summarize
The logarithmic function has no issues at values of , confirming that the domain consists solely of positive real numbers.
Final Answer
The domain of the function in interval notation is .
