@ -20,7 +20,7 @@ There are 3 places you need to worry about domain.
- There's no way to raise a number to an exponent and have it equal zero, or be a negative number.
- This can be used to help solve inequalities, because you know an equation that's wrapped in a logarithm must be $> 0$.
## Adding logarithms
### Finding the domain of added logarithms
$$ log(x+2) + log(2x-3) $$
With the above example, you can find the domain of each function separately, then find the overlap of valid numbers.
