Question

Which of the following statements is true?

An exponential function is never the inverse of a logarithmic function.

The base of the logarithmic function f(x) = log5x is unknown.

The range of the logarithmic function f(x) = log5x is all real numbers.

The domain of the logarithmic function f(x) = log5x is all real numbers.

Answer 1

if no base is specified we assume the base of logx to be 10..
upon that logic the 3rd option is the only correct statement..

Answer 2

thank you!!!
