Question 632485: The function f is one-to-one. Find its inverse. State the domain and range of both the function
and the inverse function.
13) f(x) = sqrt (x + 4) - 5.
f-1(x) =

f%28x%29+=+sqrt+%28x+%2B+4%29+-+5
f-1(x) =x%5E2%2B10x%2B21
Domain f(x) [-4, inf), Range f(x) [-5, inf)
Domain f-1(x)[-5, inf), Range f-1(x) [-4, inf)
