# Thread: Domain of a function

1. ## Domain of a function

Hi,

I was just wondering if I was on the right way. I have this function that I need to find the domain f(x)=-7/2x+5

I think the domain would be (-infinity, -5/2) u (-5/2, infinity)

If the function is $f(x)=\frac{-7}{2x+5}$ then your answer is correct.
