    Im not doing AS/A2 but Access.

    Was told this wouldnt come up in my exam but a different maths tutor has told her class it will be in the exam and its in my practice paper so im guessing it will be.

    show x=0 is a soloution to the intersection of the graphs y=f(x) and y=f^-1(x)

    I understand functions and inverse functions but i dont really know what this question is asking me to do!

    thanks

    Are you told what f is? Otherwise it's isn't necessarily true (e.g. y=\ln x and y=e^x don't have an intersection at x=0).
