No. The domain is usually the set of Real numbers whereas the range is a subset comprising Real numbers which are either all greater than or equal to a minimum value (or LE a maximum value).
Domain of the logarithm function is the positive real numbers. Domain of exponential function is the real numbers.
The domain of your function is the set of real numbers.
The domain is all real numbers, and the range is nonnegative real numbers (y ≥ 0).
