Question

What is the domain of y=log5x

Answer 1

Answer:

The correct option is 2.

Step-by-step explanation:

The given function is

$y=log5x$

It is an logarithmic function. If a logarithmic function is defined as

$f(x)=log_a(bx)$

Where, a is base of log and b>0 is constant.

Then, the domain of the function is all real numbers greater than 0, because the logarithmic function is not defined for any negative number.

Since the given function is a logarithmic function, therefore the domain of the function is all real numbers not equal to 0.

$Domain=\{x|x>0\}$

Therefore option 2 is correct.

Answer 2

The answer is both all real numbers less than 0 and all real numbers greater than 0
