How to graph a logarithmic function and determine its domain and range.
Chapter 4: Exponential and Logarithmic Functions. Because e is often used as the base of an exponential, most scientific and graphing calculators have a button that can calculate powers of e, usually labeled ex.Finding the Domain of a Function. The easiest way to identify the range of other functions, such as root and fraction functions, is to draw the graph of the function using a graphing calculator.
The answer is: domain: x>-6; range: all real numbers. this is because log functions are the inverse of exponential functions and with exponential functions the the domain is all real numbers and the range is all real positive numbers. The inverse of that of course is that the range and domain swap for log functions.
