- ASet of real numbers
- ✓Set of positive real numbers
- CSet of integers
- DSet of natural numbers
✓
Answer
Correct option: B.
Set of positive real numbers
Since the above function can have positive real value of $y$ for all real values of $x.$
So, range is set of positive real numbers.
So, range is set of positive real numbers.
