Equation whose basic form is

*y*= b*where b is a strictly positive real number and not equal to 1.*^{x }- The number b is called the base of the exponential equation.
- The general form of an exponential equation of base b is
*y*= b^{x – h}+*k*where the parameters*h*and*k*characterize the horizontal and vertical translations, respectively, of the basic equation.

### Example

The equation *y* = 5^{x} is an exponential equation with base 5.
