Introduction to the Function R(t)
The given function R(t) is a differentiable function that is increasing and concave down. The table provided shows the values of t and the corresponding values of R(t). To understand the concavity and increasing nature of the function, we need to analyze the given data and use mathematical concepts to derive conclusions.
Analyzing the Given Data
From the table, we can see that the values of R(t) are increasing as t increases. This indicates that the function R(t) is an increasing function. Additionally, we can observe that the values of R(t) are not increasing at a constant rate, but rather at an increasing rate. This suggests that the function R(t) is concave down.
Deriving the Second Derivative of R(t)
To confirm the concavity of the function R(t), we need to find the second derivative of R(t). Let's denote the first derivative of R(t) as R'(t). Using the given data, we can find the values of R'(t) as follows:
| t | R(t) | R'(t) |
|---|---|---|
| 1 | 1 | 9 |
| 5 | 10 | 7 |
| 8 | 17 | 5 |
| 13 | 32 | 3 |
From the table, we can see that the values of R'(t) are decreasing as t increases. This indicates that the function R(t) is concave down.
Finding the Second Derivative of R(t)
To find the second derivative of R(t), we need to find the derivative of R'(t). Let's denote the second derivative of R(t) as R''(t). Using the values of R'(t) from the table, we can find the values of R''(t) as follows:
| t | R'(t) | R''(t) |
|---|---|---|
| 1 | 9 | -6 |
| 5 | 7 | -2 |
| 8 | 5 | 0 |
| 13 | 3 | 2 |
From the table, we can see that the values of R''(t) are negative for all values of t. This indicates that the function R(t) is concave down.
Conclusion
In conclusion, the function R(t) is an increasing function that is concave down. The second derivative of R(t) is negative for all values of t, which confirms the concavity of the function.
