Question

The function f(x) = In(x) has a domain of all real numbers greater than zero and a range of all real numbers. The

inverse of this function is f^-1(x) = e^x

Which conclusion can be drawn by comparing the two functions?

The domain of f^-1(x) is all real numbers and the range is all real numbers.

The domain of f^-1(x) is all real numbers greater than 0 and the range is all real numbers.


The domain of f^-1(x) is all real numbers and the range is all real numbers greater than 0.


The domain of f^-1(x) is all real numbers greater than 0 and the range is all real numbers greater than 0.

Answer 1

The domain of f–1(x) is all real numbers and the range is all real numbers greater than 0.
