So f( ( x ) ) ( x+x=4 ) Please Cive your feed back.
4 If f(x)=[x]- XER, where [x] denotes the greatest integer function, then: (1) Both Lim f(x) and Lim f(x) exist but are not equal. X- 4 X 4+ ( Lim f(x) exists but Lim f(x) does not exist . X4+ (311 is continuous at x=4. (4) Lim f(x) exists but Lim f(x) does not exist. X- 4 X 4*
