.
Domain specifies the values 'x' can take.
The only thing we have to worry about is if the denominator goes to zero.
.
So, set the denominator to zero and solve for x:
x^3-4x = 0
x(x^2-4) = 0
.
So, the denominator goes to zero if:
x=0 or x^2-4=0
.
Therefore,
x = all real numbers EXCEPT: x=0, x=-2, x=2
