Kua tāruatia ki te papatopenga
x+1\geq 0 x-2<0
Kia ≤0 rawa te otinga, hei ≥0 tonu tētahi o ngā uara o x+1 me x-2, hei ≤0 anō tērā atu, otiia tē taea ai hei kore te x-2. Whakaarohia te tauira ina tōraro tahi a x+1\geq 0 me x-2.
x\in [-1,2)
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left[-1,2\right).
x+1\leq 0 x-2>0
Whakaarohia te tauira ina tōrunga tahi a x+1\leq 0 me x-2.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x\in [-1,2)
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
