Answer:
No
Explanation:
An exponential function is defined as an equation which takes the form of 
 where a is any real number and b is any positive number not equal to 1.
 where a is any real number and b is any positive number not equal to 1.
Hence, the base of an exponential function cannot be 1.
You can also deduce that if the base is 1, then 
 is equivalent to
 is equivalent to 
 The equation y=a is a linear function (and not an exponential function).
 The equation y=a is a linear function (and not an exponential function).
