Math Problem Statement
اختر (صواب) أو (خطأ) للعبارة الآتية: التمثيل البياني للدالة y = (1/2)^x هو (صواب أم خطأ؟)
Solution
To solve this question, let's analyze the given information.
The problem states:
- Equation:
- Graph: The question asks if the given graph represents the equation .
Step-by-Step Analysis:
-
Function Type:
- The equation represents an exponential decay function because the base is between 0 and 1.
- This type of function generally decreases as increases.
-
Expected Graph Shape:
- For :
- As , (the graph approaches the x-axis from above).
- As , (the graph rises sharply for negative values).
- For :
-
Graph Observation:
- The graph shown in the image appears to be increasing as increases, which is characteristic of an exponential growth function, not exponential decay.
- This suggests the graph might represent a function like , where the base is greater than 1, rather than .
Conclusion:
The statement in the question is false. The graph does not represent the function .

- What are the characteristics of exponential growth and decay functions?
- How does the base of an exponential function affect its graph?
- What are some real-world examples of exponential decay?
- How can we determine the y-intercept of an exponential function?
- How do transformations affect the graph of an exponential function?
Tip: For exponential functions, if the base is between 0 and 1, the function represents decay; if the base is greater than 1, it represents growth.
