Let R be the set of real numbers and f : R R be given by f ( x )= | x | - (1+| x |) . We now make the following assertions: I. There exists a real number A such that f ( x ) A for all x II. There exists a real number B such that f(x) B for all x
Options
- AI is true and II is false
- BI is false and II is true
- CI and II both are true
- DI and II both are false
Correct answer
B. I is false and II is true
