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

If f from R into R defined by f(x)=x^(3)-1, then f^(-1){-2, 0, 7}=

If f:[0,1] to [-1,3] defined by f(x) =x^(2)+x+1 , then f is

If A = {5,6,7}, B = { 1,2,3,4,5} and f : A rarr B is defined by f(x) = x -2, then the range of f is ......... .

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.

Let A = { 1,2,3,4} and B =N .Let f : Ato B be defined by f (x) =x^(2) +1 then the range of f is :

Let A={1,2,3,4}, B={2,4,6,8} . If f : A rarr B is defined by f(x)=2x , show that (f^-1)^-1=f
