Asked by Anne

Can someone tell me this is right?

Look for the domain.

f(x)=log(sub3)(5x+1)
5x+1<=0
(5x/5)<=(-1/5)
x<=(-1/5)
x>(-1/5)
(-1/5,oo) -domain
Answered by Reiny

Thank-you!
Answered by Reiny
actually your second line should have said

5x+1 > 0

I just looked at your answer.

Do I need to change it in each line after the second line?
