Best ResponseYou've already chosen the best response.6If \((a,b)\) is a point on \(f(x)\), then \((b,a)\) will be a point on its inverse.

Best ResponseYou've already chosen the best response.6Next, recall the transformation rule for reflection over line \(y=x\) : \[(x,y)\longrightarrow (y,x)\]

Best ResponseYou've already chosen the best response.0i dont understand. if you understand the inverse function, why wouldn't the graph make sense?

Best ResponseYou've already chosen the best response.6so, if two graphs are "symmetric" about the straight line \(y=x\), then they must be inverses of each other

Best ResponseYou've already chosen the best response.2I don't understand the shape of the graph, how can you tell if it is inverse?

Best ResponseYou've already chosen the best response.6lets find inverse of below graph : dw:1439961068302:dw

Best ResponseYou've already chosen the best response.6Clearly, there is no easy way to find the inverse algebraically, you're forced to use geometry here

Best ResponseYou've already chosen the best response.6can you guess how the graph of inverse should look like ?

Best ResponseYou've already chosen the best response.6That's a very good "wrong" guess, remember, we want to reflect it over line \(y=x\), not over x axis

Best ResponseYou've already chosen the best response.6let me just give you the answer, maybe you can try next example ok
