**Task:**
Find the exponential function that represents the graph shown.
**Graph Description:**
The graph presented is a downward-sloping exponential curve, starting from high positive values on the left and approaching zero as it moves to the right. The x-axis ranges from -5 to 5, and the y-axis ranges from -2 to 18. The red curve demonstrates exponential decay.
**Multiple-Choice Options:**
1. \( f(x) = \frac{1}{2} \cdot 4^x \)
2. \( f(x) = 4 \left( \frac{1}{4} \right)^x \)
3. \( f(x) = 2^x \)
4. \( f(x) = 4 \left( \frac{1}{2} \right)^x \)
**Explanation of the Graph:**
- The graph shows exponential decay, typically characterized by a function where the base of the exponent is between 0 and 1.
- The behavior of the graph suggests it matches one of the given functions based on its asymptotic trend towards the x-axis.
**Conclusion:**
Analyze the functions to determine which one represents the graph accurately. Functions with a base of less than 1 in the exponent will show decay, similar to the red curve in the graph.
