The domain of the function y = 3 ln x is (0, ∞) .
- In mathematics, the logarithmic function is the inverse of power.
- The domain of a function is the set of inputs or x-values on which the function is defined.
The graph of the function y = 3ln x is given below .
Then , coordinate point (1, 0)
The logarithmic function y = log x has the domain x > 0 (or) (0, ∞).
This is a logarithmic function. An important property of logarithms is that the domain cannot be denied. The same is true for x=0, since the logarithm of negative numbers is undefined.
The image attached shows the graph of this function, there you can notice its domain restriction.
