no
what is the greatest value what can get x ?
zarkam21:
6
zarkam21:
oh so choice b ? :)
jhonyy9:
yes - but why ? can you explain it me ?
zarkam21:
Yes because 6 is the greatest value and the parenthesis means that its an open circle

that it is the greatest value you can get
jhonyy9:
open circle mean that this value not can get just approach
jhonyy9:
ok ?
zarkam21:
yes makes sense so it would be choice b?
jhonyy9:
yes sure

jhonyy9:
clearly why ?
zarkam21:
because 6 is the largest value and choice b shows that?
jhonyy9:
and what is with -4 ?
zarkam21:
its the smallest value ?
zarkam21:
that is allowed

zarkam21:
but i don't understand the difference between choice b and d?
jhonyy9:
x < 6
-4 <= x
jhonyy9:
in case of C x can get the -4 value but 6 not can get
in case of d x not can get -4 but can get 6
zarkam21:
right so from that explanation i would say that it is b?
jhonyy9:
yes bc. from this -4 <=x result that x can be equal or greater than -4
and from this x < 6 result x is smaller than 6 so not can get 6
