Let's analyze the statements based on the information provided:

1. **Function A is Linear**
- **False**: You mentioned that Function A is an exponential function. Therefore, it is not linear.

2. **The rate of change of Function A is always 1/2**
- **False**: As Function A is exponential, its rate of change is not constant. In exponential functions, the rate of change increases or decreases as x changes.

3. **The value of Function B increases by 1.5 when the value of x increases by 1**
- **True**: Checking the table for Function B:
- From -7 to -6: y goes from 1.5 to 3 (increase of 1.5)
- From -6 to -5: y goes from 3 to 4.5 (increase of 1.5)
- From -5 to -4: y goes from 4.5 to 6 (increase of 1.5)
- From -4 to -3: y goes from 6 to 7.5 (increase of 1.5)
- Therefore, the value does consistently increase by 1.5.

4. **The rate of change of Function B is Always 1.5**
- **True**: As shown above, the difference in y-values is consistently 1.5 for each unit increase in x.

5. **Function B is linear**
- **True**: Since the rate of change is constant (1.5), Function B can be described as linear.

6. **Function B has a constant growth factor of 1.5**
- **False**: While the increase in y is constant (1.5), a constant growth factor typically refers to a multiplicative change, which is not applicable here since we have additive changes.

Based on this analysis, the **true statements** are:

- The value of Function B increases by 1.5 when the value of x increases by 1.
- The rate of change of Function B is Always 1.5.
- Function B is linear.
