We have the next function
![f(x)=\sqrt[]{x-2}](https://img.qammunity.org/2023/formulas/mathematics/college/guqzqamlhncz3566zdmjz6wx2sb82gztnp.png)
The domain is the set of all possible values that x can have in this case we need to remember that we can have a negative value for the radical therefore the domain is

In interval notation

a) [2,inf)
Then for the range is the set of all the possible values that the function can have in this case the range is

In interval notation

b) [0,inf)
Then we need to find the inverse of the function given, we make f(x)=y
![y=\sqrt[]{x-2}](https://img.qammunity.org/2023/formulas/mathematics/college/amrkxd1gku8t043bw0kdmy4e0wxe4occ5g.png)
Then we make x=y and y=x
![x=\sqrt[]{y-2}](https://img.qammunity.org/2023/formulas/mathematics/college/dl08o9skyogkp9cffmpryjqu7a9q3wg5ng.png)
Then we isolate the y

The domain of this function is

c) (-inf,inf)
The range of this function is

d) [2,inf)
Then as we calculate before the inverse function of the function given is

e) f^-1(x)=x^2+2
ANSWER
a) domain of f: [2,inf)
b) range of f: [0,inf)
c) domain of f^-1: (-inf,inf)
d) range of f^-1: [2,inf)
e) f^-1(x)=x^2+2
