    Kuwa makini na jinsi notation ya muda imeandikwa! Maelezo katika sehemu hii inaonekana sawa na sehemu iliyopita, lakini si sawa. Kwa kuangalia notation karibu inakuwa wazi kwamba mwisho wa kushoto haujumuishwa katika kuweka wakati mwisho wa kulia umejumuishwa katika kipindi.

    Kielelezo Template:index

    Mwisho wa kushoto, unaofanana na nambari ya 2 sio wakati. Mwisho wa mwisho, unaofanana na namba 5 umejumuishwa. Mifano ya idadi katika seti hii ni 3, 4, 4.5 na 5

    Kielelezo Template:index

    Mwisho wa kipindi hiki hufanya njia sawa na mfano 1. Wakati graphing, kumbuka mahali\(\bullet\) wakati endpoint ni pamoja na\(\circ\) wakati endpoint ni pamoja na. Baadhi ya mifano ya idadi katika kipindi hiki ni -3.99, -2, 0 na 10.

    Zoezi Template:index

    Chora mstari wa nambari kwa vipindi vifuatavyo na uorodhe angalau namba tatu ndani ya seti.
