Okay, So for this problem, we know that function f of X equals for X and are trying to find the inverse value. So basically, we're trying to find when what happens with the inverse when you plug in three. So let's kind of start by just figuring out what is the inverse of dysfunction. So it's kind of right, and that's why equals four X just to make a little easier to work with. We switched around the X and the Y and let's isolate why. So we divide these fried by four and we're left with y equals X over for that right there is the inverse. So take that here and then here we can kind of plug in this. So we plug in the three for X and we end up with 3/4 is our final answer. Check that off.
