Question 1192306: A marketing firm estimate that n months after the introduction of a client of new product f(n) thousand households will use it, where

The prompt is incomplete. To find the maximum number of households that will use the product, you need the actual function f(n).
**Here's how you would generally approach this type of problem:**
1. **Find the Derivative:**
* Calculate the derivative of the function f(n) with respect to 'n'. This will give you the rate of change of the number of households using the product over time.
2. **Find Critical Points:**
* Set the derivative equal to zero and solve for 'n'. These values of 'n' represent potential points where the maximum or minimum number of households might occur.
3. **Determine the Maximum:**
* Use the second derivative test or analyze the behavior of the derivative around the critical points to determine which point corresponds to the maximum number of households.
4. **Calculate the Maximum Number of Households:**
* Substitute the value of 'n' that corresponds to the maximum into the original function f(n). This will give you the maximum number of households that will use the product.
**Example:**
Let's say the function is:
f(n) = 100n - n²
* **Find the Derivative:**
* f'(n) = 100 - 2n
* **Find Critical Points:**
* 100 - 2n = 0
* 2n = 100
* n = 50
* **Determine the Maximum:**
* Since the coefficient of the n² term is negative, the parabola opens downwards, indicating a maximum at the critical point.
* **Calculate the Maximum Number of Households:**
* f(50) = 100 * 50 - 50² = 5000 - 2500 = 2500
**Therefore, in this example, the maximum number of households that will use the product is 2500 thousand, or 2,500,000 households.**
