What is the solution set of |x| < 11?
ok this one is a different property |a|<b implies -b<a<b
no need to write the answers, you got this:)
a) x < 11 b) x > -11 c) x < -11 or x > 11 d) x > -11 and x < 11
opps already did haha.
ok use the property I showed then tell me what we have
all good:)
example |x| < 4 so -4<x<4 so x<4 and x>-4
wait hold up.. im confused.. i got lost.
what part of my example do you not get?
its the property of absolute values |a|<b implies -b<a<b so you have |x|<11 so -11<x<11 so from this^^^^ x<11 and x>-11
think about what the absolute value is(just play with examples) and you will understand why
ya this one got me stumped
understand now?
just graph y = |x| and y = 11 |dw:1371889945675:dw| look at the graphs, where is |x| < 11 thats the solution.
so the answer is a.
not quite |dw:1371890399892:dw|
