Help.
I solved this, and I think I have the right answer, but when I plug it in it says it's wrong.
The question:
Find the domain of the function:
1/sqrt(9x+2)

here are my steps:
9x+2greater than or equal to 0
-2 -2
9xgreater than or equal to -2
divide by 9 divide by 9
finished answer: [-(2/9), infinity)
can anyone tell me where I am going wrong?
