Exponential and Logarithmic functions

An exponential function can be defined as function which has a constant base and that base is raised to a power (or exponent). These functions are increasing functions and can give huge numbers as the output. The simplest form of an exponential function is:

 Exponential functions: The simplest form of an exponential function is:

Domain:all real numbers.

Examples:

• f(x) = 3^x
• g(x) = (1/6)^xA logarithmic function is a function where a number under ‘log’ function has a base ‘b’, which when taken to the other side becomes the base for an exponential equation. The general form of a logarithmic function is shown below: Logarithmic functions: The general form of a logarithmic function is:

   

  

  Domain: (0, infinity)
