Question

How do you find the domain of `F(x)=ln(-7-4x)`?

Answer 1

Domain: `x < -7/4 or (-oo, -7/4)`

Explanation:

`F(x) = ln (-7 -4x)` Since any value for `x` in `ln x` must be greater

than zero , then domain is `-7-4x >0 or -4x > 7` or

`-x > 7/4 or x < -7/4`

Domain: `x < -7/4 or (-oo, -7/4)`
