Question

What is the domain and range of f(x)= log x-5

Answer 1

Domain : (0,∞), Range : (-∞, ∞)

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 (-∞, ∞)

Answer 2

domain is ( 0, infinity)

range(-infinity, infinity)
