The rhinoceros is one of the world’s most endangered animals. One specific species has diminished to approximately 60 rhinoceroses, and the population is decreasing at a rate of 8 percent per year. The situation can be modeled by the equation p(t)=60(0.92)t
, where p is the population of rhinoceroses after t years. Which of the following statements about the key features of the exponential graph for this situation are true?
Statement #1: As t increases, p increases slowly at first, then quickly.
Statement #2: The y-intercept is greater than 0.
Statement #3: There is a horizontal asymptote at p=0
.
Statement #4: As t increases, p decreases at a decreasing rate.
Statement #5: The p-values include all real numbers.
Statement #6: The graph decreases without bound as t approaches positive infinity.

To analyze the statements one by one based on the given model \( p(t) = 60(0.92)^t \), we can clarify the behavior of this exponential decay function.
1. **Statement #1:** As \( t \) increases, \( p \) increases slowly at first, then quickly.
- **False:** This function represents population decay; it decreases rather than increases.
2. **Statement #2:** The y-intercept is greater than 0.
- **True:** At \( t = 0 \), \( p(0) = 60(0.92)^0 = 60 \), which is indeed greater than 0.
3. **Statement #3:** There is a horizontal asymptote at \( p = 0 \).
- **True:** As \( t \) approaches infinity, \( p(t) \) approaches 0, behaving asymptotically.
4. **Statement #4:** As \( t \) increases, \( p \) decreases at a decreasing rate.
- **True:** The exponential decay function decreases, but the rate of decrease slows down over time.
5. **Statement #5:** The \( p \)-values include all real numbers.
- **False:** The population \( p(t) \) will always be positive, so the \( p \)-values only include positive real numbers.
6. **Statement #6:** The graph decreases without bound as \( t \) approaches positive infinity.
- **True:** The population continues to decrease and approaches zero but never actually reaches a negative value.
Based on this analysis, the true statements are **2, 3, 4, and 6**.
The correct response is: **The true statements are 2, 3, 4, and 6.**
