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.
Place each inverse next to the appropriate function

![On this page, you will find a series of mathematical functions and their respective inverses. An inverse function, denoted as \( f^{-1}(x) \), essentially reverses the operation of the original function \( f(x) \). Understanding inverse functions is crucial in various mathematical contexts, including solving equations and modeling real-world phenomena.
Here are the given functions and their inverses:
1. \( f(x) = 5x + 2 \)
2. \( f^{-1}(x) = x^3 - 2 \)
3. \( f(x) = \frac{2x^2 + 5}{3} \)
4. \( f^{-1}(x) = \frac{x - 2}{5} \)
5. \( f^{-1}(x) = \sqrt[3]{x} - 5 \)
6. \( f^{-1}(x) = x^3 - 2 \) (Note: this appears twice, consider any potential error in the original representation)
7. \( f(x) = \sqrt[3]{x} + 2 \)
8. \( f(x) = x^3 - 5 \)
Understanding these functions involves:
- Recognizing the notation of functions and inverses.
- Applying algebraic manipulation to solve for inverses.
- Identifying patterns and relationships between original functions and their inverses.
This visual representation is particularly useful for students learning about the concepts of functions and inverse functions. It's important to note the diversity in function types represented here, including polynomial functions, root functions, and rational expressions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1c08cd6d-2150-4cc5-a139-43de6855ea2f%2F21e4ccba-4b0f-454c-8cfd-4e0d9af30a31%2F8ljfcvr_processed.jpeg&w=3840&q=75)
