1'! Equation 5: F01} = z (9;; {if 1:1 Exercise 1: Show that the minimum value of the function F as given by Equation 5 is attained when a = 3} Keep in mind the variable involved. the only variable involved, is a; remember also 'lat differentiation distributes over a sum. As per usual, you will want to identify the critical values of F; but don't forget to justify that the critical value you identify really does correspond to a global minimum
