Let `f:R rarr R` be defined by,`f(x)={[k-x;x le-1],[x^(2)+3,,xgt-1]` .If `f(x)` has least value at `x=-1`, then the possible value of `k` is

Let f:R to R be defined by f(x)={{:(2k-2x",",ifxle-1),(2x+3",",iffxgt-1):} If f has a local minimum at x=-1, then a possible value of k is

Let f:""RrarrR be defined by f(x)={(k-2x , if xle-1),( 2x+3, if x gt-1):} . If f has a local minimum at x""=""-1 , then a possible value of k is

Let f:R rarr R be defined by f(x)={k-2x, if x 1} If f has a local minimum at x=1, then a possible value of k is (1)0(2)-(1)/(2)(3)-1(4)1

f:R rarr R defined by f(x)=(x^(2)+x-2)/(x^(2)+x+1) is

f:R rarr R defined by f(x)=(x^(2)+x-2)/(x^(2)+x+1) is:

5.Let f:R rarr R be defined by f(x)=x^(2)-1 .Then find fof (2)

If f:R rarr R defined by f(x)=x^(2)-6x-14 then f^(-1)(2)=

If f:R rarr R is defined by f(x)=x/(x^2+1) find f(f(2))

f:R rarr R defined by f(x)=(x)/(x^(2)+1),AA x in R is
