    Many-One Relation Function and Its Inverse Function

    f(x)=(x+2)^2-3
    g(x)=(x-3)^2+5
    h(x)=(x+5)^2+1

    Find the inverse function of each function above and sketch both funtion and inverse function.

    (Please show me all answers of the 3 function I given, you no have to worry about I have no exercise to try, because I have a lot of exercise books. Thanks a lot.)

    Still don't understand...

    The restriction should x≥0?
    Or
    Let, stationary point=(a,b)
    The restriction should x≥a?

    If the inverse function is square root of y, we should assume square root of y are always ≥0?
