    First find all the values x CANNOT be...

    the denominator \(\ne0\), correct?

    so the eliminated value (otherwise known as the "restriction") is the value of x that makes the denominator \(=0\).

    sooo the domain is 0 or no?

    the domain of the function, is all x-values for which the function is defined. (all x-values that you can plug in into the function, without getting an undefined output) there is only 1 x-value that will give you an undefined output. this x-value is the value that makes the denominator=0 (the denominator is the "x+1" peace)

    so set the denominator=0, and solve for x, to find that one value that is not in your domain
