Question

What is the domain of the function f(x) = 2x /(3x^2− 3

Answer 1

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

Explanation:

Answer 2

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
