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.
At this site you can see an example of a base-10 logarithmic scale.In general, for any base b>0,b≠1b>0,b≠1, the function g(x)=logb(x)g(x)=logb(x) is symmetric about the line y=xy=x with the function f(x)=bxf(x)=bx. Using this fact and the graphs of the expone...
Define and graph logarithmic functions Describe the asymptote of a logarithmic function Find the domain and range of an logarithmic functionDefinition of a LogarithmThe logarithm of a number aa, called the argument, with base bb is the number xx where bx=abx=a. In other words, a logarithm is...
Logarithms are a mathematical operation that takes a number and returns the exponent required to equal that number as a power, for a fixed base. Logarithms are the inverse of exponential functions. What is a real world example of a logarithmic function? Logarithmic scales are used to measure qu...

must be raised to produce a given number. Ifnx= a,the logarithm ofa,withnas the base, isx;symbolically, logna = x.For example, 103= 1,000; therefore, log101,000 = 3. The kinds most often used are the common logarithm (base 10), the natural logarithm (basee), and the binary lo...
Therefore, the domain of the logarithm function with base b is(0,∞)b is(0,∞). the range of the logarithm function with base b is(−∞,∞)b is(−∞,∞).In our first example we will convert logarithmic equations into exponential equations....
