Best ResponseYou've already chosen the best response.0A = {\[{x:2\le x1\le4,x \in R} \]} and B = {\[x: 5 \le x1 \le 2, x \in R\]} Represent AB on a number line.

Best ResponseYou've already chosen the best response.1\[A=\{x:2\le x1\le4,x \in R\}\] solve for x get \[A=\{x:1\le x1\le5,x \in R\}\]

Best ResponseYou've already chosen the best response.1that was wrong, solve for x get \[A=\{x:1\le x\le5,x \in R\}\]

Best ResponseYou've already chosen the best response.0yeah, start with drawing both A and B then remove the B part of the line what is left is AB

Best ResponseYou've already chosen the best response.1similarly \[B=\{x:4\le x\le3,x \in R\}\]

Best ResponseYou've already chosen the best response.0@satellite73 do we ignore the leftover part from B to the left of 1 ?

Best ResponseYou've already chosen the best response.0so the numbers that come under AB are.....? (just clarifing)

Best ResponseYou've already chosen the best response.0shouldnt it be (4,5)? :/

Best ResponseYou've already chosen the best response.0It should be (3,5) because A is (1,5) and B is (4,3) dw:1331393158512:dw Just cancel out the common part. Did u get it from the figure?
