    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)

    Thanks for your help

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

    But please, please learn to post correctly.
    You could at least use grouping symbols.
