Respuesta :

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

Answer:

What is the range of the function?  "All real numbers"
