Best ResponseYou've already chosen the best response.2You 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 dw:1439333738245:dw

Best ResponseYou've already chosen the best response.2now 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 dw:1439333883509:dw notice how I simply shifted the "z < 2" graph upward
