Answer:
I don't know the answers, but I think I know how to get them.
Step-by-step explanation:
If you have a protractor, you can use that to measure the angles.
For this case we have the following transformation:

Using the transformation we have that the image is:

Therefore, making use of this information, we can find the coordinates of the pre-image
We have then:

From here, we clear x:

On the other hand we have:

From here, we clear y:

The coordinates of the pre-image is:
Answer:
A point that is the pre-image is:
Answer:
I dont know if you mean .05, but if you do mean that it would be the hundredths place. (if this isnt the right one I'm sorry.)
The given function is

The inverse function is

To get the inverse, we swap each x and y coordinate.
The rule is 
So that's why the point (0,1) becomes (1,0) for instance.
