Let f(x) = 1/(x + 2) for x > -2, and f(x) = 1/(x + 2) for x < -2. (f(x) is not defined at x = -2 .) Which integer is not in the range of f(x)?
We have a low over high situation in terms of polynomials.....when this happens there is a horizontal asymptote at y = 0
So.....0 is not in the range of the function
