If `f(x)=x` for `x le 0=0` for `x t 0`, the f(x) at x=0 is

If f(x) = x for x le 0 = 0 for x gt 0 , then f(x) at x = 0 is

If f(x) = x for x le 0 = 0 for x gt 0 , then f(x) at x = 0 is

If f(x ) = x "for" x le 0 =0 "for " x gt 0 then f(x) at x=0 is

If f''(x) le0 "for all" x in (a,b) then f'(x)=0

If f''(x) le0 "for all" x in (a,b) then f'(x)=0

If f(x)=x sin ""1/x"for "x ne 0, f(0)=0" then at x"=0, f(x) is

If {(f(x) = 1-x), (for 0 lt x le 1),(= k , for x = 0)} is continuous at x = 0, then k =

Given f(x) = 2x, x > 0 , 0 , x le 0 then f(x) is ........

Let f be a continuous function satisfying f '(l n x)=[1 for 0 1 and f (0) = 0 then f(x) can be defined as (a) f(x)={(1 , "if"x le 0 ),(1-e^(x), "if" x gt 0 ):} " " (b) f(x)={(1,"if" x le 0 ),(e^(x)-1,"if" x gt 0):} (c) f(x)={(x,"if" x lt 0),(e^(x),"if" x gt 0 ):} " " (d) f(x)={(x,"if" x le 0 ),(e^(x)-1,"if" x gt 0):}
