How to find the domain and range algebraically for

f(x) = x-2 x 2-3x+2Also at 2 = 2 2 - 2 c/0 undefined Intermediate form so Domain ( - 00 1 1 ) U ( 1 , 2 ) U ( 2 , 0 ) Similarly lim fins = lim m-2 = 1 m -9 2 2 7 2 (2- 2 ) ( 2+ ) 2-1 so in Range space , does Not lie as 712) is Not defined Range is ( - 00 , 0 ) U ( 0 , ! ) V ( 1 , 0 )
