Omg, pls don,t kp relyng...this precalculs..u ned to knw better dis b4 mstring lnear calculus..
1.) x^2+9x+14>0
by factoring;
(x+7)(x+2)=0
x=-7; x=-2
----l-----------l------0
-7 -2
inequality x+7)(x+2) >0
x<-7 (-) (-) =+ >0..satisfy
-70 ...does not satisfy
x>-2 (+) (+)=+>0.....satisfy the ineq
solution set: {x/(x<-7,x>-2)} domain all nos less than-7 union all nos more than -2;
graph:
//////////o-----------------o////////////l0///////
x -7 -2 x
open interval
