if f(x)=x^2 1. what is the equation for f^1(x)
....f^1(x)= +/ (squareroot all)x+1
...f^1(x)= +/ (squareroot all )x1
....f^1(x)= +/ (squareroot x only) x+1
....f^1(x)= +/ (squareroot x only) x1

Best ResponseYou've already chosen the best response.0\[y=x^21\] switch x and y \[x=y^21\] solve for y \[x+1=y^2\] \[y=\pm\sqrt{x+1}\]

Best ResponseYou've already chosen the best response.0but this is not a function, so cannot be one of the answers. did they restrict the domain of f?

Best ResponseYou've already chosen the best response.0then there is a mistake here some place. you cannot write \[f^{1}(x)=\pm\sqrt{x+1}\] because a function cannot have two answers. on the other hand you are not allowed just to pick one
