Answer:
Since the independent variable x is not the exponent, 
 does not represent an exponential function.
 does not represent an exponential function. 
Explanation:
The general expression of an exponential function is 
 , where a > 0 and a ≠ 1
, where a > 0 and a ≠ 1 
Now the given function is 
 ..... (1)
 ..... (1) 
So, we can say that the function f(x) = y is not an exponential function as x is not in power of any constant. 
Therefore, since the independent variable x is not the exponent, 
 does not represent an exponential function. (Answer)
 does not represent an exponential function. (Answer)
