\frac{ x }{ x+3 } > 09
Tohaina
Kua tāruatia ki te papatopenga
\frac{x}{x+3}>0
Whakareatia te 0 ki te 9, ka 0.
x<0 x+3<0
Kia tōrunga ai te otinga, hei tōraro tahi a x me x+3, hei tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te x me te x+3.
x<-3
Te otinga e whakaea i ngā koreōrite e rua ko x<-3.
x+3>0 x>0
Whakaarohia te tauira ina he tōrunga tahi te x me te x+3.
x>0
Te otinga e whakaea i ngā koreōrite e rua ko x>0.
x<-3\text{; }x>0
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
