### Match the Exponential Function with its Graph

Below are four exponential functions and their corresponding graphs. Match each function with the correct graph.

#### Graphs:
**Graph I:**
- The graph shows a decreasing curve that starts above the x-axis and moves downward to the right, approaching zero but never crossing the x-axis. The curve is in the second quadrant then crosses to the first quadrant.

**Graph II:**
- The graph depicts a decreasing curve that starts above the x-axis and moves downward as it travels right, approaching the x-axis but never crossing it. The curve starts high in the second quadrant and drastically drops.

**Graph III:**
- The graph illustrates an increasing curve that starts near zero (but never touches the x-axis) and moves upwards as it moves to the right. The curve resides in the first quadrant.

**Graph IV:**
- The graph shows a decreasing curve that starts high above the x-axis and moves downward as it travels right, approaching but not touching the x-axis. The graph starts high in the first quadrant and gradually decreases.

#### Functions:
(a) \( f(x) = -2^x \)  
    ---Select graph--- [I, II, III, IV]

(b) \( f(x) = -2^{-x} \)  
    ---Select graph--- [I, II, III, IV]

(c) \( f(x) = 2^x \)  
    ---Select graph--- [I, II, III, IV]

(d) \( f(x) = 2^{-x} \)  
    ---Select graph--- [I, II, III, IV]


#### Graph Explanations:
- **Graph I:**
  - Represents a decreasing function with negative exponent, flipped vertically.
  
- **Graph II:**
  - Represents a decreasing function of the form \( 2^{-x} \).

- **Graph III:**
  - Represents an increasing function of the form \( 2^x \).

- **Graph IV:**
  - Represents a decreasing function with a positive exponent, flipped horizontally.

Match each function (a, b, c, d) with the appropriate graph (I, II, III, IV) based on the behavior and shape of the curves.
