values of y

[eshwarjayanth]

which of the following describes all the values of y for which y<y^2.

1 < y
-1 < y < 0
y < -1
1/y < 1
0 < y < 1

OA - D

[MarkMeier20]

Since y^2>0, if y<>0, we can divide the equation y<y^2 by y^2 without changing the < sign:
1/y<1 (D)

[casperkamal]

I think the best way is to take the elimination approach. It is know that Y < Y^2 for all values except for -1 to 1. So keeping this assumption

we can eliminate all the 4 unwanted choices zeroing on the right choice.
