Answer with Step-by-step explanation:
We are given that a function
Domain of f(x)=[-9,)
The inverse of given function
a.We have to find the domain of
We know that domain of f(x) is convert into range of and range of f(x) is convert into domain of
If we substitute x=-9 in the given function then we get
Therefore, range of f(x) =[-3,)
Domain of
b.Range of f(x) is restricted .Therefore, domain of must be restricted because range of f(x) is converted into domain of and range of f(x) is restricted.
