**Match Each Function with a Key Aspect of Its Graph** =====================================================

Understanding Key Aspects of Graphs

In mathematics, particularly in algebra and calculus, understanding the key aspects of a graph is crucial for analyzing and interpreting functions. A graph is a visual representation of a function, and it provides valuable information about the function's behavior, such as its domain, range, and critical points. In this article, we will explore the key aspects of a graph and match each function with its corresponding key aspect.

Key Aspects of a Graph

x-Intercept: The x-intercept of a graph is the point where the graph intersects the x-axis. It is the value of x where the function's y-value is zero.
Vertex: The vertex of a graph is the point where the graph changes direction. It is the maximum or minimum point of the graph.
Axis of Symmetry: The axis of symmetry is a line that passes through the vertex and divides the graph into two symmetrical parts.
Domain: The domain of a graph is the set of all possible x-values for which the function is defined.
Range: The range of a graph is the set of all possible y-values for which the function is defined.

Matching Functions with Key Aspects

1. x-Intercept of 52

Function: f(x) = 52
Key Aspect: x-Intercept
Explanation: The function f(x) = 52 is a horizontal line that intersects the x-axis at x = 52. Therefore, the x-intercept of this function is 52.

2. Vertex at (3, 5)

Function: f(x) = (x - 3)^2 + 5
Key Aspect: Vertex
Explanation: The function f(x) = (x - 3)^2 + 5 is a quadratic function that has a vertex at (3, 5). The vertex is the point where the graph changes direction, and in this case, it is the maximum point of the graph.

3. Vertex at (-3, -4)

Function: f(x) = -(x + 3)^2 - 4
Key Aspect: Vertex
Explanation: The function f(x) = -(x + 3)^2 - 4 is a quadratic function that has a vertex at (-3, -4). The vertex is the point where the graph changes direction, and in this case, it is the minimum point of the graph.

4. x-Intercept of 45

Function: f(x) = 45
Key Aspect: x-Intercept
Explanation: The function f(x) = 45 is a horizontal line that intersects the x-axis at x = 45. Therefore, the x-intercept of this function is 45.

5. x-Intercept of 3

Function: f(x) = 3
Key Aspect: x-Intercept
Explanation: The function f(x) = 3 is a horizontal line that intersects the x-axis at x = 3. Therefore, the x-intercept of this function is 3.

Conclusion

In conclusion, understanding the key aspects of a graph is crucial for analyzing and interpreting functions. By matching each function with its corresponding key aspect, we can gain valuable insights into the function's behavior and characteristics. Whether it's the x-intercept, vertex, axis of symmetry, domain, or range, each key aspect provides a unique perspective on the function's graph.
