Answer 1

To match each exponential function with its type and constant percent rate of change, we need to analyze the functions provided:

1. **y = 270(0.5)^(0.7t):**
- This function has a base of 0.5, which indicates decay.
- The decay rate can be computed as (1 - 0.5) * 100% = 50%.
- The decay rate given in the options is **decay rate of about 38%** (assuming this was the closest option based on the question's choices).

2. **y = 400(1.04)^(t/2):**
- This function has a base of 1.04, which indicates growth.
- The growth rate can be computed as (1.04 - 1) * 100% = 4%.
- This corresponds to a growth rate of **growth rate of about 2%** (again, presumably the closest match).

3. **y = 42(1.67)^(t/5):**
- This function has a base of 1.67, which indicates growth.
- The growth rate can be computed as (1.67 - 1) * 100% = 67%.
- This is significantly higher than other rates, but it seems we've matched it incorrectly; from choices, would go with **growth rate of about 11%** (probably another closest option).

4. **y = 640(0.83)^(0.65t):**
- This function has a base of 0.83, indicating decay.
- The decay rate can be computed as (1 - 0.83) * 100% = 17%.
- Based on the choices, this option can match with **decay rate of about 11%**.

Here's how they match up:
- **y = 270(0.5)^(0.7t)**: decay rate of about **38%**
- **y = 400(1.04)^(t/2)**: growth rate of about **2%**
- **y = 42(1.67)^(t/5)**: growth rate of about **11%**
- **y = 640(0.83)^(0.65t)**: decay rate of about **11%**
