can you help me I got [0,4] which is wrong?

OpenStudy (cwrw238):

yes what you have is 0 =< x <= 4

OpenStudy (cwrw238):

but correct is x i less than 0 or x is greater than 4 (the clear circle means that the value is not included)

OpenStudy (anonymous):

x<0 U x>4 so would you write it like this?

OpenStudy (anonymous):

OpenStudy (cwrw238):
