Math Problem Statement
find function domain
Solution
To find the domain of a function, we need to determine all the possible input values (usually ) for which the function is defined. Here's a general process to find the domain:
-
Look for values that make the denominator zero (if the function involves a fraction).
- The denominator cannot be zero because division by zero is undefined.
-
Look for values that make the argument of a square root or any even root negative (if the function involves roots).
- Square roots (or any even roots) are only defined for non-negative numbers.
-
Check for values that make the logarithm argument zero or negative (if the function involves logarithms).
- The logarithm is only defined for positive real numbers.
If you have a specific function in mind, please provide it, and I can help you find its domain.
