Determine the domain of the function. f(x)= 4/x^2 a x ≥ 0 b All real numbers except 0 c All real numbers except 2 d All real numbers

The domain is A. all real numbers except 0. The domain will always be all real number except what the denominator is equal to. To find the domain, you would set the domain to zero and solve for x. So it would be x^2=0 and solve. Square root the equation. The square root of zero is 0 leaving you with x=0. Giving you the answer A. all real numbers except x=0.
Hope this helped.
