How about show your problem closer to this: Determine the domain of f(x) = 2x ------------ x(x2 - 25) or Determine the domain of f(x) = 2x/[x(x2 - 25)]. ____________________________________________________________ Factor the denominator completely. What values of x make the denominator equal to zero? Please show your work/attempts here. Last edited: Jun 2, 2014
