The logarithmic function is the inverse function of exponentiation. Visit BYJU'S to learn the formulas, important properties and rules used in logarithms with examples.
Alogarithmic functionis a function of the form which is read “yequals the log ofx, baseb” or “yequals the log, baseb, ofx.” In both forms,x> 0 andb> 0,b≠ 1. There are no restrictions ony. Example 1 Rewrite each exponential equation in its equivalent logarithmic form. The sol...
Because every logarithmic function is the inverse function of an exponential function, we can think of every output on a logarithmic graph as the input for the corresponding inverse exponential equation. In other words, logarithms give the cause for an effect....
In the example below, you’ll write a common logarithmic function for the graph shown. Remember that all the functions studied in this course possess the characteristic that every point contained on the graph of a function satisfies the equation of the function. As you have done...
Example of Exponential Function Simplify the following exponential expression: 3x – 3x+2 Solution: Given exponential equation: 3x – 3x+2 By using the property: ax ay = ax+y Hence, 3x+2 can be written as 3x.32 Thus the given equation is written as: ...
