    The global minimum of f(x) occurs at an end point of the interval if the calculus like minimum (the solution of f'(x)=0) does not lie in the interval (0,1).

    Now find the solution of f'(u)=0 (in terms of a) and use the fact that f(u)=3 (which gives a quadratic in a) and solve.

    Now how many values of a do you have and do the corresponding values of u lie in (0,1) ?
