" 1.If "A={-2,-1,0,1,2}" and "f:A rarr B" is a surjection defined by "f(x)=x^(2)+x+1" ,then find "B" ."

If A=(3,81) and f:A rarr B is a surjection defined by f(x)=log_(3)x then B=

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

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

Let A=R-{2} and B=R-{1} if f:A rarr B is a function defined by f(x)=(x-1)/(x-2) show that f is one-one and onto. Hence find f^(-1) .
