The function has a maximum value at the origin, but is not derivative at the origin (the left derivative of the partial derivative is not equal to the right derivative), negating a, d; But continuously, negative d.

1 A total of 9 people get the top three, and the sum of all people's scores is (1+3+5)*3=272 The number of people in the top three in the first class is x, the second class is 2x, and the number of people in the first class is the least, then the third class is greater than xx+2x+x<9, x<=2

3 If the first class and the second class are tied for the first place, the total score of the first or second class is not less than 1 3 points of the total score, that is, 9 points, and a class has a maximum of two people to enter the top three, the two firsts are 10 points, and the first and second are only 8 points, so a class can only get two firsts and get 10 points.

4 The score of the third shift is 27-10*2=7 points.

It is the application of linear programming and the value range of quadratic functions, and the comprehensive column formula obtains (100+x)*(1000-2x)=100*1000*(1+), and then solves it yourself.
