To determine the domain and range of a function, you need to know what the function is. Let me explain the general approach for each:

### Domain:
- The **domain** of a function consists of all possible input values (x-values) for which the function is defined.
- To find the domain, consider any restrictions, such as:
  - Dividing by zero (denominators cannot be zero).
  - Taking the square root of a negative number (if dealing with real numbers).
  - Logarithms must have positive arguments.

### Range:
- The **range** of a function consists of all possible output values (y-values) that result from the input values in the domain.
- To find the range, you need to think about what y-values the function can output based on the possible x-values in the domain.

If you provide a specific function, I can help you find its domain and range step-by-step.

Here are five follow-up questions:
1. Do you have a specific function you want to analyze for domain and range?
2. Would you like a detailed explanation on how to handle functions with square roots?
3. Do you need help understanding how logarithms affect the domain of a function?
4. Are you interested in how trigonometric functions impact domain and range?
5. Would you like me to explain domain and range for piecewise functions?

**Tip:** Always start by identifying restrictions on the domain when determining the range of a function!

Understand how to determine the domain and range of a function by analyzing restrictions on input values (domain) and corresponding output values (range). This explanation covers common cases such as square roots, logarithms, and more. Suitable for high school students in Grades 9-12.
