2.8.4 - Portfolio Item: Exponents and Exponential Functions Unit Portfolio
In this unit, we explored exponents and exponential functions, which are essential concepts in mathematics. We learned how to simplify expressions using the laws of exponents and convert between standard and scientific notation. We also explored various types of exponential functions and their characteristics, such as growth or decay.
One of the key assignments in this unit was a project in which we researched a real-world application of exponential functions. I chose to investigate how exponential functions are used in finance, specifically in compound interest and exponential growth of investments. I created a presentation that explained the concepts and provided examples of calculations for different scenarios.
Another important assignment in this unit was a quiz that assessed our understanding of the laws of exponents, converting between standard and scientific notation, and solving exponential functions. The quiz consisted of multiple choice, true/false, and short answer questions.
Overall, this unit strengthened my understanding of exponents and exponential functions and their applications in real-world scenarios. I am now confident in my ability to simplify expressions, convert between notations, and apply exponential functions to solve problems.
