Answer:
It would be the first graph because |x| >5 is solved in two cases
The first case you keep everything the same, just get rid of the absolute value bars
x>5
The second case, you need to switch the sign and make the 5 negative
x<-5
When graphing you want to put an open circle on -5, and 5 because when it is < or > you have an open circle,
You then point the arrows going which ever way your sign is going, this is why the -5 is going to the left because the < sign is pointing left, and same with the 5, the arrow is going right because the > sign is pointing right
Hope this helps ;)
