Question

Which of the following statements is true?
Answer

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

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

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

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

Answer 1

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

True.

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

False.

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

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

I dont understand this.
But is false.

If you mean it to write log₅(x), the base is 5

Is you you didnt write a base, but you write log5x, the base is 10.

But if is ln(natural logarythm), the base is euler.
