Answer: OPTION C
Explanation:
An exponential parent function is the simplest form of the exponential function. This is:
By definition, you have:
- The values of y are positive for all values of x.
- As x increases, the values of y increases too with no bounds.
- As x decreases, the values of y approaches zero.
Therefore, the domain is all real numbers and the range is all positive numbers and never zero.
The answer is the option C.
