Help −2 < (1/x) ≤ 1 Whats the interval notation set? My idea is to reciprocal all of them so... -(1/2)< x ≤ 1 But i dont think thats correct... Help Thanks.

Directrix (directrix):

Assuming x is positive, x < -1/2, x is greater than or equal to 1. In interval notation, (- 00, -1/2) U [1, 00)

OpenStudy (anonymous):

why is x<-1/2...in the question it was (1/x) ≤ 1 and (1/x)> -2
