Answer:

Option c - The domain of the logarithmic function f(x)=\log_5x  is all positive real numbers.

Step-by-step explanation:

Given : Following statements.

To find : Which of the following is true?

Solution :

a. The base of a logarithmic function can be a negative number.

False, because the base of a logarithmic function is greater than 1.

b. A logarithmic function is the inverse of a rational function.

False, because the inverse of the logarithmic function is an exponential function.

c. The domain of the logarithmic function f(x)=\log_5x  is all positive real numbers.

True, because the domain of the logarithmic function  y=\log_bx  is the set of positive real numbers and the range is the set of real numbers.

d. The base of a logarithmic function can be zero.

False, because the base to zero is when solved by exponent then it became 0 to the power which is always zero.

Therefore, Option c is true.
