This module was designed and written with you in mind. It is here to help you to assess our knowledge on the different mathematics concepts previously studied and your skills in performing mathematical problems. These knowledge and skills will help you understand one-to-one functions. As you go through this lesson, think of this important question: “How one-to-one functions represents real life situations”? To find the answer, read, understand and perform the provided activities.

In this module, the learners are expected to demonstrate understanding of key concepts of inverse functions, exponential functions, and logarithmic functions. Learners should also be able to apply concepts of inverse functions, exponential functions, and logarithmic functions to formulate and solve real-life problems with precision and accuracy.

The module

After going through this module, you are expected to:

1. determine if a function is a one-to-one.

2. identify real-life situation using one-to-one function.
