Here's Alan's answer......http://web2.0calc.com/questions/math-problem_17

[ I don't see what he did, but I'm pretty sure that you and I are correct....no solution to the second part of the problem as it was presented...!!!]

I am sticking with my first answer - I think that the algebra is correct

My original graph had the wrong coefficients so it was incorrect ***

This graph is correct and it shows that there are no values for      $$f^{-1}(6)$$

So I still say there are no solutions.    Because  x=6 is not in the domain of the invese function !

 

What answer did Alan get?

------------------------------

 

Also  Chris the whole graph is of no consequence because there are restrictions on the range of the inverse fuction,

y>3   therefore    x<0    therefore   $$f^{-1}(6)$$   does not exist.
