Question
The range of the exponential function is _________.
- y = 0
- y > 0
- y < 0
- -1 < y < 1
Hint:
The range for positive function is always greater than 0
The correct answer is: y > 0
The range of the given function = y>0
since exponential function is a positive function and 5.2 is also positive
