x+2\geq 0 x+7<0
Kia ≤0 rawa te otinga, hei ≥0 tonu tētahi o ngā uara o x+2 me x+7, hei ≤0 anō tērā atu, otiia tē taea ai hei kore te x+7. Whakaarohia te tauira ina tōraro tahi a x+2\geq 0 me x+7.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x+2\leq 0 x+7>0
Whakaarohia te tauira ina tōrunga tahi a x+2\leq 0 me x+7.
x\in (-7,-2]
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(-7,-2\right].
x\in (-7,-2]
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
