A swimming pool has one intake gate and one discharge gate. A pool can be filled with water after 4 hours of water intake, and a pool can be finished after 6 hours of water discharge. When the water in the pool accounts for one fourth of the full pool, the intake gate and the discharge gate are opened at the same time. The opening time of the two gates is expressed by XH, and the percentage of the water in the pool is expressed by y (1) Find the functional relationship between Y and X, and write out the value range of the independent variable x; (2) Ask for the opening time of the two gates when the pool has one quarter of the water to one half of the water I feel like I'm going to be an idiot I can't do my homework

1. A mathematical problem of quadratic function in junior high school (speed) China is one of the countries with serious water shortage in the world. In order to enhance the residents' awareness of water saving, a municipal water supply company charges for the residents' water consumption by taking the household as the unit. That is to say, users with water consumption less than 10 tons (including 10 tons) per month will be charged a yuan per ton; users with water consumption more than 10 tons per month will still be charged a yuan per ton, and users with water consumption more than 10 tons will be charged a yuan per ton, The charge is B yuan per ton (b > A). If a household uses X tons of water per month, it should charge y yuan. The functional relationship between Y and X is shown in the figure 1. For the value of a, how much should a household charge for using 8 tons of water last month? 2.
