    Parameters- probably trivial

    Hi,
    I'm awful confused on this, and can't find anything in my notes to help.

    Find a parametrization of the form x=x(t) and y=y(t) for

    y^2=x-1 , y\geq 1

    I don't understand how or what I'm suppose to do, if someone could shine some light I'd be really grateful.

    x = t^2 + 1

    y = t

    t \geq 1
