The graphs with equations http://mapleta7.eps.surrey.ac.uk:808...kipaopgngm.gif and http://mapleta7.eps.surrey.ac.uk:808...plafpdjmch.gif meet at two points. At one of these points, http://mapleta7.eps.surrey.ac.uk:808...jijlbkpdha.gif. What is the value of http://mapleta7.eps.surrey.ac.uk:808...gmiemniapm.gif at the other point?

I dont know how to do this question, I think i should set them equal to each other,

any help appreciated.
