Question

Locate the absolute extrema of the function on the closed interval [-2;2]
f(x)=[[x]]

Answer 1

correct me if i am wrong but y=x is a straight line and so whatever y value you put in you will get the same x value so the extrema here is -2 and 2 but someone needs to confirm this

Answer 2

@abdullah1995 you got it right. I was confused because of the sign [[ ]]
Thank you :D
