Question

What does log(0) equal?

Answer 1

`log(0)` is undefined.

Explanation:

Basically you are trying to find a value of `x` such that `e^x = 0`.

As a real valued function `e^x` maps `(-oo, oo)` to `(0, oo)`, so its inverse, `log`, maps `(0, oo)` to `(-oo, oo)`.

`log(x)` is undefined for `x <= 0`
