Rate of Change
The relation between two quantities which displays how much greater one quantity is than another is called ratio.
Slope
The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:

![### Problem 9: Understanding the Behavior of a Function as x Approaches 0
**Question:**
What value is the function approaching when the function is getting closer to \( x = 0 \)? Explain.
**Graph Explanation:**
The image contains a plot of a parabolic function. The x-axis ranges from -4 to +4 and the y-axis ranges from -4 to +4. The graph is a symmetric parabola opening downwards, with its vertex at the point (0, 4).
**Detailed Analysis:**
- The function displayed in the graph is a downward-facing parabola.
- The vertex of the parabola, the highest point on the graph, lies at \( (0, 4) \).
- As \( x \) approaches 0 from either the positive or negative direction, the values of the function get closer to 4.
**Conclusion:**
When \( x \) gets closer to 0, the function is approaching the value 4. This conclusion is drawn by observing the vertex of the parabola, which represents the maximum value the function reaches.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8ca7c5d5-f13b-42ce-9aa6-2ab9d831268c%2Fa0ef1bdb-88e3-46a4-895d-fa695abd8633%2Ffrwniwo_processed.jpeg&w=3840&q=75)
