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

If A={0,pi/6,pi/4,pi/3,pi/2} and f:Ato B is a surjection defined by f(x)=cosx then find B.

If A = {1, 2, 3, 4} and f: A to R is a function defined by f(x) = (x^(2) -x+1)/(x+1) then find the range of f.

If A={3, 0, 1, 2} and f:A rarr B is an onto function defined by f(x)=3x-5, then B=

If f: R to R is defined by: f(x-1) =x^(2) + 3x+2 , then f(x-2) =

If f: R to R is defined by f(x)=(x^(2)-4)/(x^(2)+1) , then f(x) is

A={-1,0, 1, 2}, B={2, 3, 6} . If f from A into B defined by f(x)=x^(2)+2 , then f is
