Out of the four choices, it would be A
Sqrt[x] = -x
x= x ^ 2
x - x^2 = 0
-x(x-1)=0
x(x-1)=0
x = 1 or x = 0
sqrt 1 isn not equal to 0
x= 0
Half of a circle
1 circle=360
1/2 circle=360/2=180
1/2 circle cut into 1/3
180 times 1/3=60
60 degreees
0 < /6/ (absolute value)
That is your inequality since the subject is about the distance away from zero then using common sense you would make the 6 get put in between the 2 absolute value lines ( not trying to be rude, if the explanation seems rude to you im sorry)
