2/10 in simplest form is 0.2
Answer: Choice D) 
The steps to finding the inverse will have us swap x and y. Afterward, we solve for y

------------------------------
Extra info:
The inverse relation is not a function because of the plus minus. For instance, plugging x = 4 into
leads to y = -3 and y = 3 simultaneously. You would have to apply a domain restriction on
to make it a one-to-one function, to make the inverse a function. One possible domain restriction is
which would lead to the inverse function
