Question

How can you restrict the domain of the function f(x)=|x+4|-2 so the range of the inverse function f^-1(x),is [-4, )

Answer 1

The range of the inverse has to match the domain of the original function. We want to have
`f^(-1)(x)` map to
`[-4,\infty)`, so we restrict the domain of
`f(x)` to this interval.
