Money matters: Using compound interest formulas

Graphing exponential and logarithmic functions

Exponential and logarithmic functions are related to one another, but they’re quite different from the algebraic functions such as polynomials, radical functions, and rational functions. Algebraic functions all use the variable as the base of action. Exponential functions have the variable in the exponent (hence, the name), and logarithmic functions have the variable in the argument (there’ll be no disagreement there — I explain arguments later in this chapter)!

Here, you practice using these new functions and simplify expressions that have exponential and logarithmic terms and factors in them. Solving equations of exponential and logarithmic functions takes some different types ...
