1. First off, N is the variable, so that means it can be any number, and when it uses the word <em>greater</em>, it means to ADD another number, which means one point greater.
The domain of the function in this case will be for when the denominator is different from zero: 3x ^ 2- 3 = 0 3x ^ 2 = 3 x ^ 2 = 3/3 x ^ 2 = 1 x = + / - 1 Therefore the domain of this function are all reals without including x = 1 and x = -1
