Question

What is the domain of `y=log_(2)x`?

Answer 1

The domain is all the permissible x values in your function.

Explanation:

The log of any number smaller or equal to 0 is undefined. By the property `log_an = (logn)/(loga)`, we see that when n is equal to 0 or smaller, it is not defined. As a result, the domain is `x > 0`.

Hopefully this helps.
