#### Problem 3:

**Function:**
\[ f(x) = \left(\frac{7}{2}\right)^{-x} \]

**Table of Values:**

| x  | y                      |
|----|------------------------|
| -2 | \( \left(\frac{7}{2}\right)^{-2} = 12.25 \) |
| -1 | \( \left(\frac{7}{2}\right)^{-1} = 3.5 \)  |
| 0  | \( \left(\frac{7}{2}\right)^{0} = 1 \)    |
| 1  | \( \left(\frac{7}{2}\right)^{1} = 0.2 \)  |
| 2  | \( \left(\frac{7}{2}\right)^{2} = 0.8 \)  |

**Graph Description:**
The graph beside the table is a blank grid intended for plotting the function \( f(x) = \left(\frac{7}{2}\right)^{-x} \) as per the values in the table. The x-axis ranges from -3 to 3, and the y-axis from -9 to 9.

#### Problem 4:

**Function:**
\[ f(x) = 2\left(\frac{1}{4}\right)^{-x} \]

**Table of Values:**

| x  | y                     |
|----|-----------------------|
| -2 | \( 2\left(\frac{1}{4}\right)^{-2} = 32 \) |
| -1 | \( 2\left(\frac{1}{4}\right)^{-1} = 8 \)  |
| 0  | \( 2\left(\frac{1}{4}\right)^{0} = 2 \)   |
| 1  | \( 2\left(\frac{1}{4}\right)^{1} = 0.5 \) |
| 2  | \( 2\left(\frac{1}{4}\right)^{2} = 0.125 \)|

**Directions:**
Circle each function that is an example of exponential decay (there are exactly five of them). Graph each of these decay functions only.

Functions provided:
1. \( f(x) = 2 \left(4\right)^x \)
2. \( f(x) = 3 \left(5\right)^x \)
3. \( f(x) = 6 \left(\frac{2}{3}\right)^x \)
4. \( f(x) = 5 \left(\frac{3}{2}\right)^x \)
5. \( f(x) = 9^{-x} \)
6. \( f(x) = \left(\frac{7}{2}\right)^{-x} \)
7. \( f(x) = 2 \left(\frac{1}{4}\right)^x \)
8. \( f(x) = 5 \left(\frac{3}{7}\right)^x \)

Circled functions indicating exponential decay:
- \( f(x) = 6 \left(\frac{2}{3}\right)^x \)
- \( f(x) = 5 \left(\frac{3}{2}\right)^{-x} \)
- \( f(x) = 9^{-x} \)
- \( f(x) = \left(\frac{7}{2}\right)^{-x} \)
- \( f(x) = 2 \left(\frac{1}{4}\right)^x \)

**1) Function: \( f(x) = 6 \left(\frac{2}{3}\right)^x \)**
