    Is it all real numbers less than zero?

    is there any number that would make this function undefined?

    any number greater than 0, 0 is a horizontal asymptote

    oh alright. well here is the actual question. Which of the following is true? The base of a logarithmic function can be a negative number. The range of the function f(x) = log5x is all real numbers. The base of a logarithmic function can be zero. The domain of the function f(x) = log5x is all real numbers less than zero.

    I've ruled out the 3rd, and now the fourth option

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