Answer:
Domain : (0,∞), Range : (-∞, ∞)
Step-by-step explanation:
The given function is f(x) = ㏒ x - 5
We have to find the domain and range of this function.
Domain : Since logarithmic functions are not defined for the negative numbers.
So for x < 0, f(x) is not defined.
Therefore, domain of f(x) will be (0,∞)
Range : Since for any value of x > 0, f(x) is defined
Therefore, range of the function will be (-∞, ∞)
