4x+3=0
4x=-3
x=-3/4
OpenStudy (anonymous):
x=-3/4
OpenStudy (anonymous):
The domain of 4x + 3 is ALL real numbers. You can plug in any number safely without getting any problems.
OpenStudy (anonymous):
And aroub/nancy: even if you were solving for x, we don't have any assurance that it's 4x+3 = 0, so you can't just assume.

Nancy Lam and aroub ignoring the prompt lol

its all real like uber said btw
OpenStudy (anonymous):
Domain, by the way, means "what x values can I plug in without causing any problems?"
For example: \[\sqrt{?}\] 's domain would be everything from 0 upwards to infinity. Anything below 0 would have a fake answer.

oh okay. Thanks
OpenStudy (anonymous):
Yup. Since it doesn't say 3x+4 = 0, we have to assume it's 3x+4 = y
Which means we can put anything in there to get any real output.
