    Finding limits from graphs
    1. limx5f(x)\lim_{x \to -5^-} f(x)
      limx5+f(x)\lim_{x \to -5^+} f(x)
      limx5f(x)\lim_{x \to -5} f(x)
      f(5)f(-5)
    2. limx2f(x)\lim_{x \to -2^-} f(x)
      limx2+f(x)\lim_{x \to -2^+} f(x)
      limx2f(x)\lim_{x \to -2} f(x)
      f(2)f(-2)
    3. limx1f(x)\lim_{x \to 1^-} f(x)
      limx1+f(x)\lim_{x \to 1^+} f(x)
      limx1f(x)\lim_{x \to 1} f(x)
      f(1)f(1)
    4. limx4f(x)\lim_{x \to 4^-} f(x)
      limx4+f(x)\lim_{x \to 4^+} f(x)
      limx4f(x)\lim_{x \to 4} f(x)
      f(4)f(4)
    5. limx5f(x)\lim_{x \to 5^-} f(x)
      limx5+f(x)\lim_{x \to 5^+} f(x)
      limx5f(x)\lim_{x \to 5} f(x)
      f(5)f(5)
