A is the answer to your question
You can see graph of the function
in the first picture. Now to find its inverse, we are going to switch
and
in our function, and then solve for
Remember that every time that you take a square root, you will have tow results: one positive and one negative. Therefore, our function
will have tow inverses:
and
.
In the first picture you can see the graph of the original function; in the second one the graphs of its inverses, and in the third one all the graphs together. Notice that our original function is a quadratic function, and quadratic functions don't have inverse functions unless their domains are restricted.
I think it's B. Because he spends his 300 dollars so he would have to subtract it will all the money he has spent.
