    Do not bother. I just thought better of it. For the first case, y = - 3; so, it is not dependant on x. Hence, we are safe to say the range of values starts from - 3 since y is - 3.

      You use "(" when the inequality uses less/greater than, while you
      use "[" when the inequality uses less/greater than OR EQUAL TO.
      Examples:
      x < 2 = D(-∞, 2)
      x ≥ 3 = D[3, ∞)
      3 < x ≤ 8 = D(3, 8]
      2 ≤ x ≤ 6 = D[2, 6]

      @@August00098 hmm, it's been so long I have forgotten T-T, but my assumption is put open circle only if you've reached the limit given on the condition, on the video it was 4 and -1

    x --> + infintity, means x aproaches infinity from the right !!!!! not from the left !!! this is completely wrong

    • @frost.707
      @frost.707 5 років тому

      What? no. It means x is approaching positive infinite.

    • @hunterknutson2665
      @hunterknutson2665 4 роки тому

      bahahahah, no. how could a value approach positive infinity from the right? that would mean X is greater than infinity, i.e. not possible. Think about that for a second...

    • @madmaxrex7563
      @madmaxrex7563 3 роки тому

      X approach + infinity means it approach from the left, and x approach - infinity means it approach from the right.
