To find the domain of a function, here are some easy steps to follow:
Look for Limits: Check for values that might cause problems. For example, division by zero or square roots of negative numbers can lead to issues.
Write Down Rules: If you have a fraction, make sure the bottom number (denominator) is not zero. If you’re dealing with square roots, the number inside (called the radicand) has to be zero or more.
Make a Range: Use the information you found to show the domain as a range of numbers.
By doing these steps, you'll know which values are safe to use!
