Domain 0f
Range 0f
Explanation:
We know that anything divided by 0 is undefined or infinity and square root of negative numbers is not real . So we need to ensure that value of r is not equal to 0 or any negative numbers since it would not result in real values.
Therefore, Domain 0f
Since the denominator is positive (as accepts only positive values) hence the function would always return a positive real number.
Therefore, Range 0f
