Answer 2

Your answer is correct

Answer 3

When you talk about the inverse of a function, you are talking about the reflection of the function across the line its equation is y=x.
Swap every x with y, ex: point (-3,5)....its inverse is (5,-3)
So r is the inverse of the equation q.

and more ....
to get the domain and range of the inverse function, just swap the domain and the range of the original function.

Answer 4

For our case:
original function q:
domain:
\[[0,-\infty[\]
range:
\[[-5,\infty[\]

inverse function r:
domain:
\[[-5,\infty[\]
range:
\[[0,-\infty[\]

Answer 5

Conclusion:
You are correct!
