Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
number 13
![### Problem Statement
**13.** \( f(x) = x^3 + 9x^2 - 10x + 2 \) about \( x = 3 \)
### Explanation
In this problem, we are given a cubic polynomial function:
\[ f(x) = x^3 + 9x^2 - 10x + 2 \]
The task involves analyzing or evaluating this function near or at the point \( x = 3 \). The context suggests this might be part of a larger topic, possibly involving evaluation, analysis, or sketching the behavior of the polynomial around this specific value.
### Further Analysis
To understand the behavior of \( f(x) \) at \( x = 3 \), consider the following steps which might be explored in different educational settings:
1. **Evaluation at \( x = 3 \):** Calculate \( f(3) \) to determine the function's value at this point.
2. **Derivative Analysis:** Find \( f'(x) \) if the task involves exploring the rate of change or the slope of the tangent at \( x = 3 \).
3. **Graphical Interpretation:** Plotting the function for a range of \( x \) values around 3 could help visualize its nature, such as intercepts, turning points, and inflection.
