Are we supposed to be finding a function?

anonymous · Answer

yes .... i already did the problem but idk how to do domain several ppl tried to explain it but i just dont understand it

anonymous · Answer

use mathway type in the equation and click on find the domain

anonymous · Answer

it also explains how to do the problem

anonymous · Answer

never heard of mathway thank you

joannablackwelder · Answer

I can't help with the domain unless I know what the function is. Is it f(x)/g(x)?

anonymous · Answer

yup! :)

joannablackwelder · Answer

The domain of a function is all of the values of x for which the function is real.

joannablackwelder · Answer

And the only way to have unreal functions is to have a zero in the denominator (division by zero) or a negative inside an even root.

joannablackwelder · Answer

Since this problem doesn't have any roots, let's think about the division by 0 possibility, ok?
