OpenStudy (dtan5457):

I gave you your intervals x<=4 x>=4 just see which numbers match those guidelines ^

OpenStudy (dtan5457):

still can't figure it out?

OpenStudy (clamin):

i figure it out...the answers are -4,4,-5,5

OpenStudy (clamin):

idk how -5,and 5 are one of the answers

OpenStudy (dtan5457):

Just plug it into x^2>=16 5 and -5 ^2 make 25, which is greater than 16, yes?

5 > 4 and -5 < -4
