Logarithmic EquationsCh5 Compounded Interest & Present ValueChapter 2 introduces the concept of functions, focusing on their definitions, domains, and compositions. A function is a relation between inputs and outputs where each input has a unique output. The domain of a function refers to the set of all possible input values. Composition of functions involves combining two or more functions where the output of one function becomes the input of another.Chapter 3 covers linear functions and their applications. Lines are represented by equations of the form y=mx+by = mx + by=mx+b, where m is the slope and b is the y-intercept. Linear functions are widely used in real-world situations, as discussed in Applications of Linear Functions. The chapter also explores quadratic functions, which are represented by equations of the form y=ax2+bx+cy = ax^2 + bx + cy=ax2+bx+c, and systems of linear equations, which involve solving multiple equations simultaneously. Non-linear systems are also addressed, along with their real-life applications.Chapter 4 focuses on exponential and logarithmic functions. Exponential functions involve growth or decay over time and are essential in fields like biology and finance. Logarithmic functions are the inverses of exponential functions and are used to solve exponential equations. This chapter also explores solving both exponential and logarithmic equations.Chapter 5 discusses compounded interest and present value, critical concepts in finance. Compounded interest involves earning interest on both the initial principal and previously earned interest, while present value helps determine the current worth of a future sum of money.
