Marla and jimmy disagree on how to restrict the domain of the function f(x)= x 2 fx=x2 so that it will be invertible. marla claims that if you restrict the domain of f(x) fx to be x≥0 x≥0 , then the inverse of the function is f −1 (x)= x √ f-1x=x . jimmy claims that if you restrict the domain of f(x) fx to be x≤0 x≤0 , then the inverse of the function is f −1 (x)=− x √ f-1x=-x . which statement provides a correct analysis of the claims marla and jimmy have made?
a both claims are correct because both domain restrictions result in the function f(x) fx being invertible.
b marla's claim is the only claim that is correct.
c jimmy's claim is the only claim that is correct.
d both claims are incorrect because there is not a domain restriction that can be applied to f(x) fx in order to produce an inverse function of f(x) fx .
