Answer
The exponential function with base b is defined by\[y={{b}^{x}}\], \[b>0\ \text{and}\ b\ne 1.\ \]
Work Step by Step
Exponential functions are similar as that of the simple functions but the major difference in simple functions and the exponential functions is that in case of the exponential function variable is there in the power rather than in base.
In general, the exponential function is represented by\[y={{b}^{x}}\]
Here, the base is the fixed number and power is variable.
For example, an exponential function with base 2 is:\[y={{2}^{x}}\]
