You should get z >= 2 OR z < 2. That is correct. But there's more to the story.
Draw out a number line with 2 on the number line
z >= 2 has this graph
and z < 2 has this graph
now imagine overlaying or combining the two graphs to form one big graph
when we say "z >= 2 OR z < 2" we can pick either graph which allows us to combine them into one graph
that combined graph is this
notice how I simply shifted the "z < 2" graph upward
at this point, hopefully you see what the answer is?
oh, so is it all real numbers? @jim_thompson5910 sorry for the late response i was cooking dinner :P
that's ok and yes, the combined graphs make the set of all real numbers
@isaac4321 , yep welcome to highschool buddy! lol
