The image asks to find the inverse of the following functions:

### a. \( F(x) = \sqrt{x + 6} \)

To find the inverse, follow these steps:
1. Replace \( F(x) \) with \( y \):
   \[ y = \sqrt{x + 6} \]
2. Swap \( x \) and \( y \):
   \[ x = \sqrt{y + 6} \]
3. Square both sides:
   \[ x^2 = y + 6 \]
4. Solve for \( y \):
   \[ y = x^2 - 6 \]

Thus, the inverse is:
\[ F^{-1}(x) = x^2 - 6 \]

---

### b. \( F(x) = \sqrt[3]{2x - 6} \)

1. Replace \( F(x) \) with \( y \):
   \[ y = \sqrt[3]{2x - 6} \]
2. Swap \( x \) and \( y \):
   \[ x = \sqrt[3]{2y - 6} \]
3. Cube both sides:
   \[ x^3 = 2y - 6 \]
4. Solve for \( y \):
   \[ 2y = x^3 + 6 \]
   \[ y = \frac{x^3 + 6}{2} \]

Thus, the inverse is:
\[ F^{-1}(x) = \frac{x^3 + 6}{2} \]

---

### c. \( F(x) = \frac{-4x + 2}{2x + 5} \)

1. Replace \( F(x) \) with \( y \):
   \[ y = \frac{-4x + 2}{2x + 5} \]
2. Swap \( x \) and \( y \):
   \[ x = \frac{-4y + 2}{2y + 5} \]
3. Cross-multiply:
   \[ x(2y + 5) = -4y + 2 \]
4. Expand both sides:
   \[ 2xy + 5x = -4y + 2 \]
5. Collect all terms involving \( y \) on one side:
   \[ 2xy + 4y = 2 - 5x \]
   \[ y(2x + 4) = 2 - 5x \]
6. Solve for \( y \):
   \[ y = \frac{2 - 5x}{2x + 4} \]

Thus, the inverse is:
\[ F^{-1}(x) = \frac{2 - 5x}{2x + 4} \]

---

### d. \( F(x) = \frac{3}{5} (2x + 3) \)

1. Replace \( F(x) \) with \( y \):
   \[ y = \frac{3}{5}(2x + 3) \]
2. Multiply both sides by 5:
   \[ 5y = 3(2x + 3) \]
3. Expand:
   \[ 5y = 6x + 9 \]
4. Solve for \( x \):
   \[ 6x = 5y - 9 \]
   \[ x = \frac{5y - 9}{6} \]

Thus, the inverse is:
\[ F^{-1}(x) = \frac{5x - 9}{6} \]
