Elementary functions in mathematical problems
(1) Two analytical expressions are combined into a set of equations, and x=36 and y=34 are obtained.

Therefore, we will stabilize the price of 36 yuan and the demand for 340,000 pieces.

(2) As can be seen from the figure, y 1 is less than y2, and when x is greater than 36 and less than or equal to 70, the demand for this drug is lower than the supply.

(3) When y 1=34+6=40, x=30.

So 36-30=6

Therefore, the government should provide 6 yuan subsidies for each drug to make the supply equal to the demand.
