a) Calculate g₀(s) as given in (??) for the decision problem in example 2 with a_k
= a and b_k
= b, 1 ≤ k ≤ n. Verify (??) and (??).

b Upper bound Q(x) by substituting y = z x for z as the variable of integration in the integral defining Q(x) and then dropping the quadratic term in y. Explain why this results in a good approximation for larege x (nothing very elaborate is expected here).
