![**Title: Understanding Functions in Graphical Form**
**Introduction:**
In this lesson, we will decide whether the relation defined by a graph defines a function and determine its domain and range.
**Does the Graphed Relation Define a Function?**
- **No**
- **Yes** (✔️)
**Explanation:**
To determine if the graphed relation is a function, we can perform the Vertical Line Test. If any vertical line intersects the graph at more than one point, the relation is not a function. If every vertical line intersects the graph at most once, the relation is a function.
In the provided graph, every vertical line intersects the graph at most once, hence the relation defines a function.
**Graph Explanation:**
The graphed relation depicted is a blue curve on a coordinate plane with:
- The x-axis ranging from -6 to 6.
- The y-axis ranging from -10 to 10.
- The graph shows a continuous curve that starts from the lower left quadrant, moves upwards crossing the y-axis once, forms a peak around (0, 6), descends to form a trough around (-4, 0), and ascends up to the right quadrant.
**What is the Domain of the Graphed Relation?**
To find the domain, look at the extent of the x-values covered by the graph. The graph extends indefinitely along the x-axis in both directions.
- **Domain:** (Type your answer in interval notation.)
**Solution:**
The domain is all real numbers because the graph continues indefinitely in both the positive and negative directions along the x-axis.
- **Domain:** (-∞, ∞)
**Conclusion:**
To summarize, we determined that the given graph defines a function by using the Vertical Line Test. We also identified the domain of the function, which includes all real numbers.
**Interactive Exercise:**
- Apply the Vertical Line Test to the graph.
- Determine the range of the graphed function.
**Note:**
Understanding the domain and range of functions is crucial in the study of mathematics, as it helps in identifying the possible values that a function can take and the possible input numbers.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fee664c28-5b72-4a07-aa31-c82c4ca626a8%2Ffb483e36-08f2-47d7-b82b-fa71822017b7%2Fwymfiia_processed.png&w=3840&q=75)
