The image you've provided is an "Identifying Functions" activity, where you examine various mappings, tables, and graphs to determine if each represents a function or not.

Here's a general guide to solve this type of activity:

1. **Definition of a Function**: A relation is a function if each input (or \( x \)-value) maps to exactly one output (or \( y \)-value). In other words, no \( x \)-value should repeat with a different \( y \)-value.

2. **Analyzing Tables**: For each table:
   - Check if there are any duplicate \( x \)-values with different \( y \)-values. If so, it’s **not a function**.

3. **Analyzing Mappings**: For each mapping diagram:
   - Verify that each element in the first set (usually the \( x \)-values) points to only one element in the second set (the \( y \)-values). If any \( x \)-value points to multiple \( y \)-values, it’s **not a function**.

4. **Analyzing Graphs**: For each graph:
   - Use the **vertical line test**: if a vertical line intersects the graph in more than one place, then it’s **not a function**.

Based on this, you can classify each section in the activity as either a "Function" or "Not a Function." 

Would you like a detailed explanation for each part in the image, or do you have specific questions about one of the sections?

Here are 5 questions that expand upon this explanation:
1. How do mapping diagrams help in understanding functions better than tables?
2. What are some real-life examples where only one output is allowed for each input?
3. Can a function have repeating \( y \)-values? Why or why not?
4. How does the vertical line test relate to the definition of a function?
5. What would the opposite of a function look like in real-world scenarios?

**Tip:** When analyzing functions in different formats, always look for consistency in \( x \)-values mapping to a unique \( y \)-value as the first step!

Identify which of the given tables, mappings, and graphs represent functions in the 'Identifying Functions' activity.

Learn how to determine whether a relation is a function using tables, mappings, and the vertical line test in graphs. This activity helps students identify functions by analyzing each type of representation to see if each input corresponds to a unique output. Suitable for students in Grades 8-10.
