    Katika sehemu hii, mwisho wote haujumuishwa katika kipindi hicho.

    Muda hapo juu unajumuisha namba zote kati ya 2 na 5, lakini kwa sababu muda una mabano kwenye pande zote za kushoto na za kulia za muda, pointi za mwisho hazijumuishwa.

    \((-4,10)\)

    Sawa na maelezo ya mifano ya awali, pointi za mwisho hazijumuishwa katika kipindi. Hivyo muda unajumuisha kila namba kati ya -4 na 10, lakini si -4 na 10.

    Kwa sasa, wanafunzi wanapaswa kuwa na wazo kubwa la namba ambazo zinajumuishwa na hazijumuishwa katika mifano hapo juu. Wanafunzi wanapaswa pia kuwa na uwezo wa kuchambua mstari wowote wa nambari na kuandika nukuu inayofaa ya muda kwa mstari wa namba hiyo. Jaribu mazoezi yafuatayo ili uangalie ufahamu.

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

    1. \((0,1)\)
    2. \((-11,-5)\)
    3. \((100,325)\)
    4. \((5,6)\)
    5. \((12.1, 26.55]\)

    Chora mstari wa nambari unaofanana na vipindi vifuatavyo.

    1. \([-2,3)\)
    2. \([-5,-2]\)
    3. \((0,5]\)
    4. \((-3,4)\)
    5. \([-3,-2]\)
    6. \((-7,2.5)\)

    Andika notation sahihi ya muda kwa mistari ya nambari iliyotolewa.
