Answer:

The correct answer to your query is the first choice.

Explanation:

The reason for it being; domain: x > 0; range: all real numbers is due to the fact that displayed on a graph (Simply plugging the equation into Desmos), we can see that the domain (In F(x), it would be the x), never reaches a number higher than zero, meaning it is smaller than. As for the range, we see that at any point it is a real number, so the range is all real numbers.

The domain of the function is given by:

x > 5.

And the range is the set of all real numbers.

How to find the domain and range of the function?

Here we want to find the domain of:

f(x) = log(x - 5).

You need to remember that the logarithmic function can only be evaluated in positive arguments, then the argument of our function must be positive, this means:

x - 5 > 0

Solving for x, we get:

x > 5.

This defines the domain.

And the range will be the same as the range of the log(x) function, which is the set of all real numbers.
