What are the domain and range of the logarithmic

function f (x) = log7X? Use the inverse function to

justify your answers.

The domain of f is x > 0.

The range of f is all real numbers.

The domain of the inverse function is all real numbers.

The range of the inverse function is y > 0.

The domain of f is the same as the

range of the inverse function.

The range of f is the same as the

domain of the inverse function.
