The wire of length a is folded into a rectangle, the analytic expression of rectangular area y with respect to side length x is obtained, and the domain of definition and value of this function are written out Domain I know, mainly for the range

The wire of length a is folded into a rectangle, the analytic expression of rectangular area y with respect to side length x is obtained, and the domain of definition and value of this function are written out Domain I know, mainly for the range


y=x(0.5a-x)
Domain of definition: 0 & lt; X & lt; 0.5A
Range: 0 & lt; y ≤ A & # 178; / 16



The wire of length 2a is folded into a rectangle, and the analytic expression of the function of the area y of the rectangle with respect to the length x of one side is obtained, and the definition and value range of the analytic expression of the function are obtained


Y = 2x * (A-X) domain 0



If the wire of length a is folded into a rectangle, the functional relationship between the area y and the length x of one side is? And the definition field is?
